Subject: [PATCH 06/11] add w0rpcore nickname l0dable

This l0dable by Benedikt Roth and Stefan Tomanek serves as your main
viewscreen, displaying your nickname the way you want it, and lets the
stars zoom by. You can accelerate your vessel by pushing the joystick
upwards or bring it to a halt by pressing it down - leaving your ship
drifting in the endless space. Attach two LEDs to the modulbus
connectors (SS2->GND, SS5->GND), so your r0ket can light up its nacelles
when breaking the warp barrier.

Subject: [PATCH 07/11] improved accuracy of battery voltage measurement

Slowing down the ADC 10x while reading the voltage gives better
results due to the very high impedance of the voltage devider.
Readings are now about 100mV higher than before.
