Mostly just memory leak fixes, and win32 compatibility. Bumping the ebuild works just fine. I'm not sure what we want to do about the soversion change, it changed from 113 to 114. My view is to just remove the preserve_old_lib calls and bite the bullet.
use 1.13.99
libgsf-1.14.0 has been added I held on to the preserve calls, because it should only be a reminder to rebuild and rebuild the users should.
