This makes two changes to fix additional errors in the Review Bot config

process.
First, the integration config form was still encountering issues with

client-side validation of hidden tool options input elements on some

versions of Chrome. Instead of going through and making each element

disabled, I've changed it to just set novalidate on the top-level

form.
Second, I noticed that there was an error in the JS console when loading

the extension configuration page. This was due to the template

overriding the scripts-post block but not including the block's super,

leaving out some necessary JS files.

Exercised the extension and integration config pages.
