New Revision: 60978

URL: http://svn.reactos.org/svn/reactos?rev=60978&view=rev
Log:
[WIN32SS]
 - Commit everything I got on new cursor/icon implementation
 - Implement loading animated cursors (no display yet)
 - Get rid of this m:n relation between cursors and processes. (ie. proper implementation of LR_SHARED)
 - Get rid of the global linked list of cursors (ditto)
 - Use atoms instead of copying the module name into the object. (aka stop using non paged pool for nothing)
 - Misc fixes
