Patches are now part of the game database.

They can be CRC specific, or just based on the game serial.

Examples:
[patches]
	// This patch is loaded regardless of crc
	patch=0,EE,002aa040,word,24020001
[/patches]

[patches = 84993903]
	// Patches go here
	// This is only loaded if crc = 84993903
	patch=0,EE,002bc040,word,24020341
[/patches]


notes:
- pcsx2 only loads the first [patches] block that matches the game.
- The [patches] block based on crc takes priority when pcsx2 searches for patches...
- Everything in-between the patches block gets fed to pcsx2's old patch parser; so currently the patch syntax is the same as before...
- A lot of patches weren't added to the database since they didn't include serial codes in their *.pnach files :/
