Improved ws2812 implementation
...
- Fixes the "first led problem" (#534 #487 ).
- Adds support for 160MHz mode.
- Optimized timings. Time to write pixels is reduced by about 25%
This is useful when having a large amount of chained LEDs (>500).

app/modules/ws2812.c: re-add ws2812.write()
...
Add the original ws2812.write() function which does not scramble the
buffer while preserving the 'new' ws2812.writergb.
With this everybody should be happy again

Changed the ws2812 byte order from GRB to RGB
...
There seems to be interest in using the more intuitive RGB byte order to
specify the LED color. Also fixed the documentation.
