OfflineList 0.7

A lot of you have gotten various unclean roms from the net that have hacks in them or intro's written into them which will make it difficult if not impossible for gpSP to play them. OfflineList is an eye pleasing easy to use rom manager.
Fix from previous versions are:
* Error when launch emulator for uncompressed files.
* The option "regroup duplicate" was a general option and not a dat option.
* In some cases, when regroup files, empty archive are created.
* In some cases, when regroup files, old files are not deleted.
* The option "show files in bad archive" was not saved.
