their info from the database.

Worlds and Mongo

Worlds should now be stored in mongodb.  Also updated the handlebars
file to allow procedurally generated worlds to be made into the webpage.

Set up partials for handlebars

Set up so that anything in the partials folder is instantly recognized

value.  Also cleaned up the main handlebars file so that everything is
in a proper partial.
