add /accounts/ (get, post) routes

Slight markup changes, same style overall and same
form parameters as the PHP implementation.

In addition, we've disabled the "left" and "right"
navigation buttons when we're at the border of the
table.

CSS Changes:

- Added similar styling to submit `<buttons>` that submit `<input>` had.
- Added .results tr td[align="{left,right}"] styling to align
  the result table's `More -->` button to the right of the table.
