Shoes4 - pushing towards 1.0

by Tobias Pfeiffer for JRuby

The goal of this project is to push the shoes4 project as close as possible to a 1.0 release. Therefore the missing features of the Shoes DSL will be implemented. A focus is on not breaking the interface, since old shoes programs should still run. Backwards incompatible changes will only be made for consistency reasons or bug fixes.
