linux: several improvements to the starter script, provide a default alsoft.conf

* removed several export lines that are not supported
* added a line that -if the user enables it- lets openal load a specific alsoft.conf
* added a line that -if the user enables it- adds a custom GST_PLUGIN_PATH
* create a crashlog package in the viewer folder if stack_trace.log exists.

+# OpenAL config file. Options that are not under a block or are under the
+# [general] block are for general, non-backend-specific options. Blocks may
+# appear multiple times, and duplicated options will take the last value
+# specified.
+# The system-wide settings can be put in /etc/openal/alsoft.conf and user-
+# specific override settings in ~/.alsoftrc.
+# For Windows, these settings should go into %AppData%\alsoft.ini
+# The environment variable ALSOFT_CONF can be used to specify another config
+# override
+
+# Option and block names are case-insenstive. The supplied values are only
+# hints and may not be honored (though generally it'll try to get as close as
+# possible). Note: options that are left unset may default to app- or system-
+# specified values. These are the current available settings:
+
+## format:
+#  Sets the output format. Can be one of:
+#  AL_FORMAT_MONO8    (8-bit mono)
+#  AL_FORMAT_STEREO8  (8-bit stereo)
+#  AL_FORMAT_QUAD8    (8-bit 4-channel)

+#  AL_FORMAT_71CHN16  (16-bit 7.1 output)
+#  AL_FORMAT_MONO32   (32-bit float mono)

+#  AL_FORMAT_71CHN32  (32-bit float 7.1 output)
+#format = AL_FORMAT_STEREO16
+
+## cf_level:
+#  Sets the crossfeed level for stereo output. Valid values are:
+#  0 - No crossfeed
+#  1 - Low crossfeed
+#  2 - Middle crossfeed
+#  3 - High crossfeed (virtual speakers are closer to itself)
+#  4 - Low easy crossfeed
+#  5 - Middle easy crossfeed
+#  6 - High easy crossfeed
+#  Users of headphones may want to try various settings. Has no effect on non-
+#  stereo modes.
+#cf_level = 0
+
+## head_dampen:
+#  Sets the amount of dampening on sounds emanating from behind the listener.
+#  This is used to simulate the natural occlusion of the head, which is
+#  typically missing with mono and stereo output, and as such, only works on
+#  mono and stereo output modes. Valid values range from 0 to 1 (inclusive),
+#  and higher values provide a stronger effect.
+#head_dampen = 0.25
+
+## frequency:
+#  Sets the output frequency.
+#frequency = 44100
+
+## resampler:
+#  Selects the resampler used when mixing sources. Valid values are:
+#  0 - None (nearest sample, no interpolation)
+#  1 - Linear (extrapolates samples using a linear slope between samples)
+#  2 - Cubic (extrapolates samples using a Catmull-Rom spline)
+#  Specifying other values will result in using the default (linear).
+#resampler = 1
+
+## rt-prio:
+#  Sets real-time priority for the mixing thread. Not all drivers may use this
+#  (eg. PortAudio) as they already control the priority of the mixing thread.
+#  0 and negative values will disable it. Note that this may constitute a
+#  security risk since a real-time priority thread can indefinitely block
+#  normal-priority threads if it fails to wait. As such, the default is
+#  disabled.
+#rt-prio = 0
+
+## period_size:
+#  Sets the update period size, in frames. This is the number of frames needed
+#  for each mixing update.
+#period_size = 1024
+
+## periods:
+#  Sets the number of update periods. Higher values create a larger mix ahead,
+#  which helps protect against skips when the CPU is under load, but increases
+#  the delay between a sound getting mixed and being heard.
+#periods = 4
+
+## sources:
+#  Sets the maximum number of allocatable sources. Lower values may help for
+#  systems with apps that try to play more sounds than the CPU can handle.
+#sources = 256
+
+## stereodup:
+#  Sets whether to duplicate stereo sounds on the rear and side speakers for 4+
+#  channel output. This provides a "fuller" playback quality for 4+ channel
+#  output modes, although each individual speaker will have a slight reduction
+#  in volume to compensate for the extra output speakers. True, yes, on, and
+#  non-0 values will duplicate stereo sources. 0 and anything else will cause
+#  stereo sounds to only play out the front speakers. This only has an effect
+#  when a suitable output format is used (ie. those that contain side and/or
+#  rear speakers).
+#stereodup = true
+
+## scalemix:
+#  Sets whether to scale the remixed output. When the final mix is written to
+#  the device, the multi-channel data is remixed so pure-virtual channels (eg.
+#  front-center on stereo output) are remixed and added to available channels
+#  (eg. front-left and front-right). Scaling helps ensure that no single source
+#  will put out more than 100% on a given physical channel. This can cause a
+#  noticeable reduction in overall volume, however, so it is off by default.
+#scalemix = false
+
+## drivers:
+#  Sets the backend driver list order, comma-seperated. Unknown backends and
+#  duplicated names are ignored. Unlisted backends won't be considered for use
+#  unless the list is ended with a comma (eg. 'oss,' will list OSS first
+#  followed by all other available backends, while 'oss' will list OSS only).
+#  Backends prepended with - won't be available for use (eg. '-oss,' will allow
+#  all available backends except OSS). An empty list means the default.
+#drivers = pulse,alsa,core,oss,solaris,dsound,winmm,port,null,wave
+
+## excludefx:
+#  Sets which effects to exclude, preventing apps from using them. This can
+#  help for apps that try to use effects which are too CPU intensive for the
+#  system to handle. Available effects are: eaxreverb,reverb,echo,modulator,
+#  dedicated
+#excludefx =
+
+## slots:
+#  Sets the maximum number of Auxiliary Effect Slots an app can create. A slot
+#  can use a non-negligible amount of CPU time if an effect is set on it even
+#  if no sources are feeding it, so this may help when apps use more than the
+#  system can handle.
+#slots = 4
+
+## sends:
+#  Sets the number of auxiliary sends per source. When not specified (default),
+#  it allows the app to request how many it wants. The maximum value currently
+#  possible is 4.
+#sends =
+
+## layout:
+#  Sets the virtual speaker layout. Values are specified in degrees, where 0 is
+#  straight in front, negative goes left, and positive goes right. Unspecified
+#  speakers will remain at their default positions (which are dependant on the
+#  output format). Available speakers are back-left(bl), side-left(sl), front-
+#  left(fl), front-center(fc), front-right(fr), side-right(sr), back-right(br),
+#  and back-center(bc).
+#layout =

+#  same speakers as the layout option are available, and the default settings
+#  are shown below.
