1) Fixed crash on source files that contain zero length tags

2) Fixed a glitch in filename corrector - it sometimes didn't replace underscores with spaces.
3) Fixed a bug when a broken cue sheet was created if artist, title or genre contained comma character.
3) Added .zip archive support
4) Added support for cue sheets which start with data track (mixed mode or "playstation type" cds)
