Explicitly use components/jquery to install jquery

`jquery` used to be a shorthand to `components/jquery`, while `jQuery` referred to `jquery/jquery`.
Recently the jQuery team requested that `jquery` point to `jquery/jquery` as well.
Bugs are now open with both projects:
http://bugs.jquery.com/ticket/14798
https://github.com/bower/bower/issues/462

Until this issue is resolved, we should be explicit about what version we want.
Upgrade Backbone, Bootstrap, and jQuery-mockjax
Upgrade numerous dependencies
Remove shims for backbone and backbone-associations
Upgrade to work with latest version of backbone-associations
Update backbone-associations

Use updated version from private repo until changes are merged into the main repo.
