I propose declaring UserActionType as an enum which will be extended with
new action types gradually over time as more and more engines will be
converted to the new architecture.
Now, the real action objects (that can be declared as constant, by the way)
defined by UserAction struct (which actually contains the action type,
description, etc.) will be registered in the event manager during the
engine/game start up.
So, this is basically a dynamic approach, because each engine/game has a
list of X actions it can handle and registers/unregisters them with the
event manager during startup/shutdown.
