Run worthwhile generator - Do Not Merge

This branch runs the worthwhile generator, which enables solr, fedora, jetty, and the rest of the worthwhile engine. This is essentially a scratch space to enable our conversation with @mjgiarlo and @jcoyne tomorrow. 

We got the latest generator (from worthwhile master) to run successfully, and all migrations have been run. `rake jetty:start` seems to work. All the existing tests still pass. And that's where we've left it.
