Emulator reads now blocking.

Better error output CubeControl. Better debug output cubeEmu. cubeEmu
now supports sending data, but still hangs sometimes or doesn't answer
with OKs, etc.

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.

Audio Firmware now with Watchdog. Removed unused code. Fixed compiler
warnings. Fixed cube coordinate system problems. Fixed audio display
rotation. Nicer Idle Display with SAP Logo. Increased Firmware Version
Number. Debug Build even more talky.

Code never was rewritten for new Hardware.

This reverts commit b6b00a6bcd.

The display now gets updated with 48fps or 384 layers per second, while
the animations still play with 24fps.

Interrupt execution time does not change, strangely?

Honestly: What is this kind of shit? Do you even care the slightest bit?
