config: mouse-bindings: verify button isn't already mapped

Browse source 
A button may only be mapped to a single action. Detect when the user
tried to map the same button to multiple actions and error out.

To clear a binding (for example, to free up a button from the default
bindings), one can set the action it is bound to to
`NONE` (e.g. `primary-paste=NONE`).
