JRuby moving to Java 5

Currently JRuby supports Java 1.4.x, which is good for all us supporting enterprise customers still on this old platform (i.e.: almost every SAP customer I've come across).

For all new versions JRuby will only support Java 5. This goes for current trunk and forward.

The JRuby 1.0 trunk will stay compatible with 1.4.x, and the JRuby team will provide a Retrotranslator/Retroweaver version, slower than the 5-version, but compatible with 1.4.x.

After all this is probably the best solution for JRuby, but now I'm even more eagerly awating the enterprises of the world to move to 5.
