New features
You can now batch rename all currently loaded files, choosing among different naming schemes.
Fixed bugs
Fixed a bug that caused the cover image of a corrupt file not to be set to the default cover image. When deleting a game that is split up into 2 files, the second file is deleted, too (a second part file has extension .wbf1 or .iso.1).
