T-edition sprites/portraits patch

That's a known bug. The last 4 colors indexes into the palette aren't usable for battle and menu sprites. Egger's patch remove this limitation but it's kinda intrusive (expand the rom). So, considering how battle poses never show the Phoenix i found a compromise, keeping the red just for the "town" sprite. Unluckily a pair of cutscenes uses a battle "environment" (the espers riding Vector for example) and Locke shows his back with glitched colors.
