Change CHEF Omnibus cookbook base_uri attribute because Opscode as migrated their omnibus S3 bucket.
Temporarily roll back ember rc5. We identified some things we need to fix.
Enabled strong_parameters across all models/controllers.

All models are now using ActiveModel::ForbiddenAttributesProtection, which shifts the responsibility for parameter whitelisting for mass-assignments from the model to the controller. attr_accessible has been disabled and removed as this functionality replaces that.

The require_parameters method in the ApplicationController has been removed in favor of strong_parameters' #require method.

It is important to note that there is still some refactoring required to get all parameters to pass through #require and #permit so that we can guarantee that parameter values are scalar. Currently strong_parameters, in most cases, is only being utilized to require parameters and to whitelist the few places that do mass-assignments.

FIX: Hitting enter while the invite dialog is up should submit the form, not refresh the
entire page :)
FIX: Touch events conflicted on mobile safari with `{{action}}`s, preventing admin menu
option from working. Mobile Safari works with click so this seems to fix it.

Fix "undefined method `end_with?' for 1:Fixnum" when field name in YML file is not quoted number like:

```
    user_action_groups:
      1: "Likes Given"
