- adjust lcd_grey_phase_blit() parameter to recent change
- detection of external power
- compilation of plugins - need to be enabled individually in SOURCES/SUBDIRS 
(use autostart.rock as test plugin with limited interaction via BUTTON_POWER)
also 
- move autostart.rock to apps dir where it is expected
- set missing svn:keywords for various files

Fix empty commit: Add grayscale support for ARM in vertical packing format.

Enable grayscale for Iriver ifp. Fix timer_unregister for PNX0101.

Grayscale library: Tuned frame frequency for the 2nd/3rd gen LCD.

Grayscale lib: Using a 32x32->32 bit multiplication is better on ARM, as 16x16->32 bit isn't a single instruction. Renamed the macro for pointing out that it's not necessarily 16 bit anymore, and to avoid collisions with similar macros in plugins.

* Use fast multiplication macro in some more places. * Better pipelining on SH1.

Better implementation of the new greyscale algorithm. A bit faster (+2% on iPod and Archos, +7% on Iriver H1x0), and more straightforward. * Fixed garbage display when a plugin switches on the overlay before drawing anything.

New algorithm for grayscale buffer updates which is faster for large buffer depths. Speedup (unbuffered, depth==32): +8% on H1x0, +17% on Recorder (depth==24), and +83% on iPod Mini.
