Add filtering for Enhancement Chips
This adds filtering for Enhancement Chips with the --no-enhancement-chips
option)
ATTENTION: --no-all
doesn't include --no-unlicensed
anymore. The reason for this is that some popular platforms (e.g. NES) have a number of Unlicensed, but still desirable, ROMs, and it's easier to make the users type
--no-all --no-unlicensed
if they want to exclude both than it is to make them type
--no-bios --no-program --no-enhancement-chips --no-proto --no-beta --no-demo --no-sample
in order to exclude everything but the unlicensed ROMs.
