Various logging fix ups.

Mostly removing console spam.
Swap a bunch of info / debug logs.
Better archiver console spam.
Have some "avatar has left" mesasge hit the INFO console.
Tweak the login logging a bit, especially for impersonations.
Default to INFO on the console and DEBUG in the log files.
More time stamp resolution.
Better sim startup console notification.

Attempt to render "[LLUDPSERVER]: Malformed data, cannot parse" into
something human readable as an aid to diagnosis.  Beats hand translating
the big block of hex codes it was spewing.

Better sim startup finished messages.  Inform neighbours we are up
before the finished messages.  Always send the "[RegionReady]:
INITIALIZATION COMPLETE FOR" message.
