Party version + win32 build

This is a rough win32 port of the original AVR code.
It's the "emulator" used for developing, with most debug features stripped out.
It would also work on linux and macos (probably?) but didn't bother to compile for these platforms.

It's a bit rough around the edges, some effects are very jittery, and the timing is a bit off.

Some effects run faster than the real hardware (of course, 4x4 matrix-vector multiplication on AVR sucks),
and it might break on some machines, but I guess it works as a port.
For the real experience, watch it on hardware, or at least go watch the hardware capture.

The exe should be compatible with WinXP. Couldn't test it anymore before the deadline though.
