move the rest of Anki's code out of pystache
In the process of factoring out the field filtering, the "extra" and "fullname" args are just passed in as a blank string now. Extra was functionality that allowed a field modifier to be defined as "filtername(arg1,arg2):field", and fullname was the name of the field including any provided field modifiers. From grepping through the add-ons on AnkiWeb, neither appears to have been used.
