* Added a directory for the SVN module. More about to come.* SVNBackupModule

* See OpenSim.ini.example settings for how to use
* Only compatible with svn:// and http:// authentication for the moment (and only using simple authentication). SSL/SSH key support is supported by the library used (SvnDotNet), but is not yet supported in OpenSim.
* Use the command "svn save" to make a copy of your regions to SVN. Presently this is not an automatic process, but such a feature is on the todo list.
* It will in your repository create a subdirectory for each region with the regions UUID, inside there it will create a 'terrain load' compatible 'heightmap.r32', and a load-xml2 compatible 'objects.xml' plus information files.
* Untested on Linux, some compatibility work may be needed by Linux peoples. The dependencies will be the same as for SvnDotNet which is supposedly mono-compatible.
