Partial regions and categories

@Sammyfrw @SherrySeibel 

When on admin control board you can see the lists of regions...and
categories. I will need to hide categories on this page.
Partials should only be in `app/views/application` if it's being used in more than one controller. Otherwise they should be in the same directory as the view they're being rendered from. This should be in ` app/views/admin_options`
