Refactor actions into separate action sets (#122)

* Fix indentation in action manifest

* Rename action sets to drop unnecessary prefix notation

Since the variable is in the action_sets namespace it does not make
sense to prepend it with an identifier for it being constant, or a set.

* Rename input keys to drop prefix notation

The vars are in a namespace that only contains constant inputs, it
doesn't make sense to prepend it to every var.

* Rename actions to drop prefixes

It is implicit that actions are const values for sets, therefore the
prefix is not needed.

* Remove unneeded action set member func

* Move active action set in preparation for more action sets

* Move action strings above class

Class is not able to use variables in namespaces, which is stupid.

* Move sets into member variable

* Split music into separate action set

* Convert action_manifest.json to spaces only

* Refactor actions into separate action sets

* Rename main set to haptic

* Reorder action sets

The haptics and misc sets are misc bindings.

* format

* fixed manifest path issue

* Change path concat to use QDir

The old way was not platform independent.

* Move accessibility actions to motion set

* Remove "(Held)" from action name

Might be confusing for end users.

* Replace slash with platform independent separator

* Make paths output native paths
