Support 2.0+ of Processing for Run command

Thanks to @LFSaw, fixes #3.
Use version 1.8 of ruby for bundle items

10.7 and 10.8 only include ruby 1.8, so all bundle items have been written to work with that. Optionally supporting ruby 1.9 and 2.0 is problematic as these versions are not fully backwards compatible.

M: use processing-java for run
use /usr/bin/processing-java if exist
