Add ng-grid dependencies (pre-3.0).
Set $httpProvider.defaults.withCredentials = true.
Allow ng-including of "remote" partials; add ng-grid elements

(For now, please be content that they are loaded later and are in
separate files, even if not truly remote.)
Changes to support bulk -> bulk 2nd level -> individual item

For example, bulk review by brand -> products within the brand ->
individual item all with browser history/back button support.

Changed some config items for clarity.
