Updating the v2 Jenkins version to match the RPM'd jenkins we use

Is there any reason we wouldn't do this now?  Does it require any sort of migration?

I'm assuming test scripts that explicitly use jenkins 1.4 and jenkins-client 1.4 would need to be updated.

I checked and Online, Origin and Enterprise are all using Jenkins 1.5 now.  Makes me wonder if we should go ahead and update our RPM requirements to require 1.5 or greater since that's all we're testing with and I believe the version in the cartridge and the installed jenkins should always match.
