Patch

Currently whenever a value is changed in a context, all its listeners are notified; then it is up to the listener to determine if they need to react to the change. 

This is a somewhat expensive. For instance, polling of context listeners takes up about 25% - 30% of the time to switch active editor. 

I'd like to change how we store listeners: place them in the bins corresponding to the name they depend on. (It will be possible to have the same listener in multiple bins.)
