binary patterns
We use on/off for patterns, so I have rewritten the pattern handling,
removing the pattern_t type altogether, and changed it to use
binary strings of data instead. This uses less RAM for pattern definitions.
I have also changed blink_pattern to include morse code text
(generated by morse.pl), with kids' names.

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.
