Added drupalgap_add_js function. Added drupalgap_changePage function().
Fixed code indentation.
Added a drupalgap forms api, similar to the drupal forms api, with form state, and form errors, and replaced the user registration form by using this new api, shweeeeet. Added a core user module, so far it just holds the new user registration form api implementation. Added a 'home' button listener that pages can use to send user's to the front page of the app. Replaced all html page home button's with the new button that just utilizes a class attribute on the element so the click listener can pick it up.
