Submit/edit form tweaks

* Don't specify action on form - this is best practice and avoids the
  need to have separate form tags for submit and edit
* Add a short introduction to the submit form
* Focus first field on load only if first field is empty (avoids doing
  this focusing on the edit form which is not really useful).
