scala console and guice branches

[phausel]

hi all, sorry about the delay!

guice:
https://code.launchpad.net/~peter-kovac11/play/play-guice
-please let me know what else you need


scala console (improvements):
https://code.launchpad.net/~peter-kovac11/play/play-scala-console-improvements
what's new:
- auto completion/readline now is supported
- a transaction is launched before the console launch

as i mentioned the find methods are working just fine, the only
remaining issue is that 'save' is not working on models probably due
to class loader issues.
