Some recent changes to the configforms module added an extra

<div class="field"> inside each row. This mucked up some of the JS and

CSS used in Review Bot's integration config, which does some crazy stuff

with sub-rows in order to configure tool-specific options.
This change fixes those up to handle things correctly in either case.

Loaded the integration config page and saw that there was no longer a

  useless "Tool Options" label.
Changed the "Tool" field to a few different things and saw the correct

  tool options rows appear.
