Adjusted drupalgap_form_render to accept a JSON options object. drupalgap_setup_form now needs a page id, a form id, and a css selector within the page to attach the form to. Adjusted all calls to drupalgap_setup_form to accomodate this change. Started ib imagefield (filefield) form element implementation. Added a 'picture' element to the user profile form. Added better debugging statements to drupalgap_entity_load_into_form and drupalgap_field_info_instances.
