Consistent visual layout for forms

We should try to make most / all forms conform to the same look and feel with regard to:

• consistent css classes for form elements (top priority)

• use of fieldsets and fieldset nesting
• use of panes
• background color
• styling of labels and input elements
• computed font size
• placement of form buttons
• HTML layout method (divs with tables whenever possible)

The general "model" is the Contact Edit form (as applicable).
