[FEATURE query-params-new]

[FEATURE ember-routing-consistent-resources]

uuid is now consistently used across the project.

[BUGFIX] sync back burner: workaround IE's issue with try/finally without Catch. Also no longer force deoptimization of the run loop queue flush.

[BREAKING BUGFIX] An empty array is treated as falsy value in bind-attr to be in consistent with if helper. Breaking for apps that relies on the previous behaviour which treats an empty array as truthy value in bind-attr.

[BREAKING BUGFIX] On Controllers, the content property is now derived from model. This reduces many caveats with model/content, and also sets a simple ground rule: Never set a controllers content, rather always set it's model and ember will do the right thing.
