Links from Django forms to where they can be configured

[milescalabresi]

Admins don't like that they can't edit a form that they're looking at and they have to know in advance that they have to (for example) go to program settings on a separate page that's three clicks away. Proposal is to include a banner/text at the top of the various forms that links them to the settings page for that form. ("Want to edit this form/these fields? Click HERE.") More ambitious version for anyone excited would be a field-by-field link to where on the settings page that field is modified.

I think the biggest hurdle for this is assembling the information (in some sort of global dictionary or as some sort of attribute for each form [or even each field]). Once we have that information set, we could probably just override the default template for forms and have a banner at the top like in #3432.
