Untappd addition

I added the code to do the Untappd Rating and brewery feed. 

Currently it looks to see if the clientID and breweryID are set in the database.

Added the "form" to the personalize screen to add the clientid, client secret and brewery id.

I took a look at adding the beer id to the beer list form, however that was pretty convoluted.

(also, I tried to do this pull request against the development branch...)
