by tea.time: Merged Angular callback menu items to single path 'ngapp/%' - this variable arg allows modules to generate different custom responses via hook_ngapp_response()
by natemow: Added new drupalSettings service to wrap access to the global Drupal.settings object.
by natemow: Added Angular app name as 'id' attribute on <body> element, to support IE8 with Angular version 1.2.x and lower, if desired.
If you tried out the 1.0 release, you'll want to re-save your settings after updating - the variable structure for the drupalServices factory changed a bit in this release.
files[] are no longer required for component registration, in the case that pure Angular factories, services, directives, etc. only need to be added.
Added drupalAppPath constant so components can use Angular templateUrl and similar for paths to non-block templates.
