This commit adds the graphical Arduino IDE, built from the arduino-core
expression.
Also:
- Add libusb to RPATH for avrdude. Without this, avrdude is broken.
Possible TODO: replace bundled avrdude with the one from nixpkgs.
- Use "cp -r ./build/linux/work/*", so example sketeches, the HTML
reference documentation and the 'arduino' shell script that starts the
IDE gets included.
- Make meta.description slightly more generic, to cover both GUI/core
variants.
- replace fetchurl with fetchgit because googlecode is unmaintained
- remove unnecessary phases
- change license and maintainers
- tested with a few sketches and inotool
- change description according to "Contributors Guide"
change fetchgit to fetchFromgitHub
Closes #4449
