Introducing the native file chooser

Based on vanilla processing select_input utliity.

Release for JRubyArt-1.1.1

More samples have been updated to use data_path, more hype library examples added.

This release is the first for this repo supporting JRubyArt-1.1+

Examples here are modified to use the new data_path wrapper, instead of relying on processing (java) to find the local data folder. At least on linux, this means no need for the --nojrubywhen running shader and load_image sketches, further should solve macosx data path issues.
