Bug 8935 - transport cost matrix could be prettier

Correcting the template so that it follows established
interface patterns and coding guidelines:

- Form contents in a fieldset
- Submit button in a fieldset with class "action" and
  with a "Cancel" link.
- Errors displayed in a <div class="dialog alert">
  (no custom error classes necessary).
- Valid markup.
- No JavaScript errors (to that end, the patch removes a
  call to a non-existent function, show_transport_cost_matrix)
