All-new greyscale library, replacing the old one. Features: (1) Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update.

/* NOTE:
The user timer is used to generate a 70Hz tick for Doom. But it
is unavailable for the grayscale targets (it's used by the grayscale
is unavailable for the greyscale targets (it's used by the greyscale
lib) and is not implemented in the simulator - so we have to
approximate it using current_tick.
