The Viewport component is slow

[gregtatum]

I believe the fix here is to unhook the Viewport from dispatching actions. We should attach an event emitter to the store that operates independently of the actions. The mouse events fire way too fast to reasonably hit the store with.

Can you elaborate somewhat which actions are slow ? :)

[gregtatum]

updateProfileSelection is really hot when using mouse events, it dispatches an action really quickly, and causes unneeded component and store churn.
