Make Redate available for all games RRR

Useful for newer games, since the CK still uses modification times to
determine its load order. Also the reason why LOOT still offers the
option for newer games. However, its implementation was erronously using
attrgetter('mtime'), which hardcodes the mtime=LO assumption, making it
unusable as-is for newer games. Changed it to use our LO API instead.

Mod_Redate -> File_Redate

Preparation so that it can be added to all tabs, since it will be a must
have for the Morrowind BSA tab and I'm sure someone can come up with a
usage in other tabs at some point - plus swiss army knife and all that ;)
