Vis event handler logic should move into the renderbot

[spalger]

Currently event binding with visualizations is a bit of a mess. Click handlers for the filterbar are implemented in the visualize editor and the dashboard panel controllers, the tilemap's events are implemented in the vis type, and none of them are really conditional based on their need.

I think we should move them all into the Renderbot. The purpose of the renderbot is to tie together a kibana Vis object and a DOM node and seems like the perfect place to implement this.

This also seems like a good place to implement #2716

This needs to handle all event listeners, and remove listeners from state. They can't be serialized and shouldn't have been added to state to begin with.

Outdated.
