Changes

* Load more languages when the creating the database.  Currently it only adds English and Spanish.  There has to be a list of languages for Django, maybe a model, a portable app, or there may be inside Django itself.

** There is a list in ''books/langlist.py'' but is a very 'long list', we should make a bigger list in the ''books/fixtures/initial_data.json''

* Add feed navigation.  The OPDS spec considers two kind of feeds: 1. navigation feeds and 2. acquisition feeds.  Currently Pathagar has acquisition feeds (the ones that have the books).  This will enable the posibility to add navigation in the Get Books activity.
