* Combined the converter from <ico>.png to bitmap.hpp and reverse in one script: pp_png2hpp.py
* Minor change ficed variables from testing.
* Cleanup output for parser. Add description to readme.md
* Update pp_png2hpp.py
Added the suggested and much cleaner argparse code from zxkmm.
Added a icon-name handling, to convert one or a comma seperated subset of icons by name.
* Update pp_bitmap_parser.py
Updated the handler with dynamic in/outputs, in parallel to the pp_png2hpp.py script ... But I think I'll delete this one, after I decide how to handle the alpha (transparent) code.
