Attempt to optimise the ADD background drawing mode so it's playable on automatic frameskip in games like Super Metroid. It doesn't work well.

Mess with Mode 5 some more. Secret of Mana's menu sprite is fixed; however, as of commit 3cd20e203f (still not fixed in this commit!), Donkey Kong Country's Rareware icon is split by black columns.

Render double-width-res tiles from Background Mode 5 as half-width tiles. This makes the menu text in Secret of Mana readable.

Sprites in Background Mode 5 are still messed up. At least they're at the right X coordinate, roughly...

Rendering optimisations.
...
tile.cpp: Optimise the common case of drawing an unclipped but possibly flipped 8x8 tile. Instead of calling WRITE_4PIXELS16 16 times, each performing setup and teardown, move the loop into DrawTile16.
tile.h, tile.cpp, gfx.h, gfx.cpp: End the use of global variable GFX.ScreenColors to pass around the current frame's palette. This saves on memory stores/loads.

Speed up rendering by an unknown amount.
...
gfx.cpp, others: Avoid always checking for Settings.SixteenBit if FOREVER_16_BIT is defined.
port.h: Define FOREVER_16_BIT below PIXEL_FORMAT.

Preliminary Snes9x-based cheat code support. Not tested, because the file selection interface freezes when it gets to the folder containing Mightymo's cheat files, whereas it did not do this before with the converted Mightymo cheats. (335 files -> 679, though.)
