- in camlib.py, CNCJob class -> generate_from_excellon_by_tool() was
failing in the line to sort the tools due of been unable to compare
between dict's. I replaced that section.
- add setup.py script,
- switch to use images via "share:" resource name
(this allows to work both versions of application:
- system wide installation,
- directly from source),
- add .desktop file,
- rename FlatCAM.py to flatcam and install it as an
executable script.
