Subject: [PATCH] GSdx: CRC hacks: allow exclusion of some/all hacks via
 "hidden" ini pref CrcHacksExclusions. The list is case insensitive and order
 insensitive. E.g. Disable all CRC hacks:          CrcHacksExclusions=all E.g.
 Disable hacks for these CRCs:   CrcHacksExclusions=0x0F0C4A9C, 0x0EE5646B,
 0x7ACF7E03
