As of now, a key binding installed into a BindingPool is always there and cannot be changed. This is problematic for sub-classes trying to override the callback or the action for a given key binding. This commit adds the ability to override the closure for an existing key binding inside a binding pool -- assumed the caller knows the key symbol and modifiers used to install the key binding in the first place.
