Added taxonomy_vocabulary and taxonomy_term local task argument rewrite support to drupalgap_get_menu_link_router_path(). Adjusted drupalgap_entity_build_from_form_state() and drupalgap_entity_form_submit() to accept the form and form state then set up all of the entity form submit handlers to pass along the form and form state to these functions, thus eliminating drupalgap.form and friends. Adjusted drupalgap_entity_form_submit() to watch out for a form.action so when the success call back is fired, drupalgap_goto can have a place to go. Added taxonomy_vocabulary support to drupalgap_entity_get_core_fields(). Fixed a bunch of accidental global variable declarations. Setup 'view' and 'edit' local tasks for vocabularies, thus eliminating the need for the old taxonomy_vocabulary_edit html and js files. Updated taxonomy_form_vocabulary() to use drupalgap_entity_add_core_fields_to_form().
