Add "what the form" view

[shawnbot]

This adds a new "what the form" view that, given one of the below URL archetypes, attempts to provide as much information about the form, any options passed, and translations, as possible:

1. Any sf.gov or *sfgov*.pantheonsite.io URL will parse out the data source URL and options from the HTML
2. Any portal.form.io URL will attempt to get the project and form ID from the hash (#/project/:projectId/form/:formId), query the "Live" stage form.io API for a form with that ID via sfds.form.io/form?_id__eq={formId} (check out the form.io API docs for more info)
3. Any other *sfds*.form.io URL will be treated as a JSON data source URL

I've added support to look up pages on sf.gov by form data source URL (using an API published from our private forms repo) so that any of these should work and show the same results:

• SF.gov URL
• Data source URL
• Form.io portal URL
