Rewrote dimPalette() so that the dimming is now a "filter" between the Screen

class and the backend, i.e. as far as the game engine is concerned the palette
remains unchanged. (This is similar how to the SCUMM engine handles the "noir"
mode in Sam & Max.)

This is one small step towards allowing the game to be paused anywhere.
