Reorder compounds, 2.2.0.1b support

The compound order put Animation above Transition which Animation refers to.  This is apparently no longer supported in NifSkope and had to be reordered.

Add gitattributes

Details:
--------

Source files with conflicts (marked with "C" in the log below): resolved manually.
Conflicts in nifskope/resources: simply reverted to trunk/resources (in other words, they have been left unchanged).
Skipped files: manually copied with "svn cp" (except for nifskope/kfm.xml, which is a copy of the docsys/kfm.xml).
Missing targets: ignored.
nifskope/widgets/uvedit.cpp: reverted (i.e. no changes); something went wrong during merge, I think nothing was really changed in the file but for some reason svn failed to recognize that and applied the patch wrongly

Compiler fixes:
gl/glnode.cpp:889: tm &Matrix4 ... -> tm Matrix4 = ...
