sanni 1c6d277e84 V8.5 BETA: Add global log and GB database 
Both are disabled in options.h by default since they push the RAM usage over the limit resulting in corrupted LCD output.

Global log outputs all info to OSCR_LOG.txt in the root of the SD.

no-intro calculates the CRC32 of a Gameboy ROM and if found in the database renames it to no-intro naming scheme.
