dedicated_add_form: preliminary structure - #85

Started creating structure for new 'Dedicated Add Form' feature -- '/add'
action is set up and renders the add_form, but no biz-logic/handling code
yet ("Save" button does nothing yet)
Dedicated Add Form working - #85

The dedicated add form is now working -- submits and creates new
records. Post-create hooks not yet working (i.e. autoload_added_record)
Dedicated add form - post create logic working - #85

Post-create logic - such as autoload_added_record - now works in the
dedicated add form
Dynamic wait close for autoload_added_record - #85

Added looping/wait handling for the case of autoload_added_record in
case it is a slow post-create process. See in-code comments for details
Merge branch 'dedicated_add' - fixes #85
