Moved COLLADA-loading code into separate class, since it now handles
both PMD and PSA.
Desingletonised CSkeletonAnimManager, moved into CGameView.
Made Atlas load its icons with buffered IO, for possible efficiency.
This was SVN commit r4934.
* Changed log files to trigger standards mode in Firefox (to be
consistent with other browsers), by making it valid HTML5. Changed the
font and some spacing.
* Made CLogger default to ignoring messages if it hasn't been
initialised yet, instead of crashing.
* Added leak reporting to the unit tests.
* Renamed mods/_tests to mods/_test.xero, since it's only used by
Xeromyces and the other tests use mods/_test.otherstuff instead.
* Fixed Atlas compilation on Windows.
* Moved Atlas's DLL-loading code into a separate class, so it can be
shared.
This was SVN commit r4707.
