Adjust the width of the fields on the form submission

Adjust the width of the fields on the form submission

Did several things, including:

 - Call the individual form field rendering macros instead of the auto
   whole-form renderer so we get better control over the TextArea
 - Use the textarea specific form field rendering macro
 - Adds textarea styling to the css
 - Sets the input, textarea styling to be 460 px wide (the width of
   the form section, not including padding)
