[Rubyeclipse-commit] SF.net SVN: rubyeclipse: [1718] trunk/org.rubypeople.rdt.ui

[<caw...@us...>]

Revision: 1718
          http://svn.sourceforge.net/rubyeclipse/?rev=1718&view=rev
Author:   cawilliams

Log Message:
-----------
Add a menu item/action to "Add a Ruby nature" to an existing project. This is useful for existing Java projects where we'd like to use some ruby scripts. (So a lot of JRuby projects and also our own plugins).
This fixes problems where opening a ruby script inside a Java project made RDT throw runtime exceptions (because it did a check for Ruby nature on the project).
