[Feauture Request] verify all roms and set tags to good dump or bad dump

[shanigma]

Hello to the devs and everyone else,

first of all this emulator is perfect.

It would be very useful if there was a way to verify all Roms without checking them individually each time.

It would also be cool if it were automatically tagged with: good dump/bad dump if the status of Redump.org gives informations about that rom.

An export option of the ROM list as a Logiqx XML/DAT file with the crc32/md5/sha1 data from the file itself and the status="good" or status="baddump" if Redump.org verifiying is success.

I hope somehow it would be possible to add these functions.

Thanks and happy christmas to all
Cheers
