Quick Toggle Key Override Layers (#159)

* Allow quick enabling/disabling of all layers for a Key Override

Add small “Enable all” and “Enable none” buttons beneath the list of layers to which a Key Override applies. Clicking the buttons will enable or disable all the layer check boxes.

* Update function names

* Updated label
