DEVELOPER-933 home page ab testing

One thing that needs to happen before we merge is that the experiment needs to be created in the jboss analytics and the code needs to be swapped out. More in JIRA.

To try the variations, open the console and run either:

`app.pageVariations[0](); `

Or 

`app.pageVariations[1](); `  - this one is the styling that is different. 
looks like you didn't merge it properly.
