closes#4541
creates a handlebars helper with behavior matching the spec in #4541 and
updates `frontend.js` to include the navigation data in the rendered page
context.
- checks for {{current}} against `relativeUrl`
- adds helper `getSiteNavigation()` which returns contents of
`api.settings.read('navigation')`, or an empty list
- navigation helper is responsible for filtering and consistently formatting
navigation data from settings.
- changes `frontend.js`'s `formatResponse` & `formatPageResponse` to return
a promise with page data and updates frontend controllers to use it.
- `formatPageResponse` now includes a third parameter to allow values to be
merged into the page response (rather than using `_.extend` in the
render methods directly.
- {{navigation}} will render an empty `ul` if no navigation items exist
- incorporates {{url}}/urlFor behavior for nav contexts. (see #4862)
- uses {{url absolute="true"}} in default nav template
