Bumping version for new run-app mode

See wiki for details. Thanks to @pedrozath.

Update to use jruby-complete-1.7.25

Even the JRuby guys will probably lose interest in 1.7 series after this release, time to check out propane or JRubyArt

Polyglot maven build

2.6.17

Update README.md

Expected final release, update to jruby-1.7.23

I tried but failed to create java version that would lock toxiclibs to version-0.4.0 and pbox2d to version 0.4.2, if anyone could do that, it would warrant another release. Otherwise bye bye ruby-processing, hello JRubyArt (jruby_art)

Update to jruby-complete-1.7.22

Update rspec, introducing p5map is direct replacement of processing map which is now deprecated (use of processing map in ruby is anachronistic, and is about time we just dropped it). Use map1d or constrained_map is more ruby like 3 args vs 5 args for p5map.
