Change directory structure to align with Atmel softpack
This way we can easily check with 'diff' for differences in our code and
Atmel softpack. Also, this layout is more suitable for building various
different firmware images (e.g. factory-test, dfu-loader, main
application) for a variety of different boards (simtrace, owhw, qmod).

+ *
+ * LEDs are numbered starting from 0; the number of LEDs depend on the

+ * regardless of whether the LED is defined or not; they will simply
+ * return 0 when a LED which does not exist is given as an argument.
+ * Also, these functions take into account how each LED is connected on to
+ * board; thus, \ref LED_Set might change the level on the corresponding pin
+ * to 0 or 1, but it will always light the LED on; same thing for the other
+ * methods.
