Add genome

This PR re-bases the site to run on Rails 3.2 so you now need to run ```rails s thin``` to start the server. It has has _very_ limited testing under 3.2, so expect to see some errors if you go poking around.

The PR also includes a feature to test adding a genome that is hardcoded to use the files you refer to in the manual PDF. Both adding a genome and adding an organism are now working under Rails 3.2.

I have several questions that come up from making this work but, for now, applying this PR will get two features running under Rails 3.2. 

I'm going to add the feature "add experiment from GFF data" that's listed out next in the manual, so expect that next.

Once done I think we have enough features to test working with users.
