optimized the LED and buzzer wiring
* since we use timer 3 exclusively for the buzzer but trigger the pin
using an IRQ handler, there is no longer any need to occupy a high-resolution
pin for the buzzer.
* PD5 became a new high resolution LED
* PD0 became the new buzzer pin
* rearranged the pins used for the different LEDs so that the distribution
of high-resolution LEDs is symmetric
* Timer 0 is no longer used/modified by setting LEDs.
This avoids some workarounds as timer 0 is also used by tmk's timer module.
* The song routines could be slightly improved using the timer module.
* documented the LED and buzzer pinout in README
