Release: Alpha 23 (fixes a serious bug)

This release is only meant to fix the bug present in alpha 22, which deleted all of your backups and then crashed, if you deleted backups manually and then let DISE overwrite your old backup(s).

Just to humor you, I'll explain the problem. :)

GEEK ALERT
The buggy code:

// How many do we need to delete? Make room for the new backup
unsigned deleteCount = (backupFolders.GetCount() - maxBackupCount) + 1;

First, I missed "int" after "unsigned", but that that's not the problem (does not matter in this case). Let's say we have 10 backups, and the max is 10. After deleting 3 manually, we have 7 backups left. This is the simple math:

// How many do we need to delete? Make room for the new backup
unsigned int deleteCount = (7 - 10) + 1;

Normally, deleteCount would equal -2, but since deleteCount is so-called unsigned, it can't have negative numbers. Instead, deleteCount equals 4294967294. That's why DISE crashed. It tried to delete 4294967294 backups! (; -_-)
END OF GEEK ALERT

Anyway, I fixed it, so please get this release instead of the last one. :)
