Reinhold Gschweicher aa34f93161 sim: embedd background bmp and load from memory
Loading the file from disk introduces a slight dependency on the working
directory for the simulator. Prevent that by loading the bmp from
memory.

Use a python script to convert the backround bmp image to a C header
file. Include this header in `main.cpp` and load the bmp from memory.
