JDF-659 Fix MSIE9 error in HTML5 form validation.

We defer to server-side validation, in browsers where HTML5 Form
Validation is not supported, like MSIE 9.
JDF-660 Fix for member collection sync in MSIE

The Backbone Collection.fetch API call is now configured to
add a timestamp value to the URL. This prevents MSIE from caching
the first response and reusing it despite a stale cache entry.
JDF-569 Use HTTP interceptors to append timestamps to URLs.

This uses the HTTP interceptors feature in AngularJS 1.2 instead
of relying on the ngResource.query invocation to bypass the
caching behavior in MSIE.
JDF-578 Removed references to Aerogear from the quickstarts.

The Aerogear branding was removed where used. References to the
Aerogear site were replaced with equivalent links to the JDF site.
