HISCORE DIFF's for all MAME versions without hiscore support (108 - current)

The diff performs the following:
1) Adds hiscore support back into MAME
2) Removes all nag screens
3) Removes loading messages (decoding/decrypting/Updating Artwork, etc.) and the 'white box' when loading.

 Add the following to the mame.ini file to disable the appropiate patch section:
