Font is not pretty, but works :)

Audio CPU now resets MSGEQ7 properly. Bufferhelper clears memory after
allocation. Z Axis now goes into the correct direction. Removed
FillRect. Enabled Watchdog for Debug Build, too. Removed unneeded
strings. Built-In Framedata in own file. Makefile cleans object files
after every build, because it doesn't matter. Simple Visualization
works correctly. Most recent Hex-Files now included.

Wrote new audio visualizer. Created help functions to operate on a 3D
image buffer.

Changed some more faulty transistors. cubeInit now displays short test
animation. Moved header files in own folder.

Now talks to FRAM most of the time…

Auto select animations and frames, consistent order for frame and
animation buttons.

This was done because I was suspecting an error to be there. This is
not the case, so we probably have a Hardware Problem with our USB
Serial Stuff… If we send data too fast it sends garbage. It also always
sends two additional bytes (0xC2 at the beginning, 0xFF at the end),
which both come at the beginning if we don't delay between sending the
chars…
