Subject: [PATCH] LP1813647 Angular page title component & sandbox example

Adds a new component <eg-title /> which may be used to pass strings to
the native Angular Title service.

Each title may have a prefix and/or a suffix.  If both are defined, they
are separated by a "-" (by default / en-US) and the prefix is tructed to
12 characters, consistent with AngularJS strings.setPageTitle()
function.
