feat(behaviors): Add reusable sensor behaviors.

* Add new sensor behaviors that either take full bindings
  add definition, or accept parameters when bound in the
  keymap.
* Remove existing hard-coded key press sensor behavior
  and instead leverage new generic sensor behaviors to
  achieve the same functionality.
