Added field_info_fields and field_info_instances. Improved the forms API to use html element attribute ids similar to drupal, e.g. edit-title, edit-body, etc. Added forms api support for hidden inputs, default values, descriptions, and basic support for the text_with_summary field. Added a [form]_form_loaded mechanism that is called once the form is rendered on the page. It is used by the node edit page to retrieve a node after the form is loaded, then fill in the form with the node values. Fixed [form]_form_validate and [form]_form_submit calls to have the form and form_state now passed to it. Turned the node edit form into a drupalgap forms api form. Added 'buttons' support to the forms api.
