Added demo as a git submodule, so its easier to test stuff on your local machine
Removed unused test class
Grunt: Only copy dist files to demo if the submodule has been initialized
Ember.AnimatedContainerView now automatically queues animations, which eliminates the need for blocking the UI.

Also changed:
- Added slowSlideLeft and slowSlideRight effects, which are useful for testing with.
- Effect methods now take a callback function that they should call instead of destroying the old view themselves.
Added a convenience method, setCurrentViewAnimated, to set current view and animation effect in one call
Fixed .gitmodules for travis
Updated demo submodule
readme typo
Added a todo item
Merge branch 'master' of git://github.com/billysbilling/ember-animated-outlet into linkToAnimated
