Multi-screen API: Fixed macro checks for screen type/ depth, some cleanup. The multi-screen code doesn't handle certain combinations (which aren't found in current targets). A combination of one charcell and one bitmap lcd will make it crash, and a combination of two bitmap LCDs with a depth > 1 but different pixel formats will show wrong colours/ shades on the remote.
