Project: step-up converter

I have decided to add various projects using Tinyboard directly
to this repository. The first project is a step-up converter
with current feedback for a string of LEDs.

The firmware is a dumbed-down version of firmware for my other
project: http://www.fi.muni.cz/~kas/bike-lights/, modified
for ATtiny45.
