Improve display of the HTML Form Entry "Manage HTML Forms" page

This page could use being cleaned up and prettified.

The title of the page should be changed from "Edit Form" to "Manage HTML Forms".

The list of forms should be in the standard OpenMRS boxheader style, and we can remove the checkbox that appears next to each form name.

On the actual "Edit Form" page we should right-align all the field labels and a semi-colon after each of them.
