Bastien Bouclet df4bf6556c KEYMAPPER: Introduce custom engine actions
Custom engine actions are a new type of event the Keymapper can produce.
When an engine declares its keymap, it can declare it wants to receive
custom action events when the corresponding key is pressed, instead of
the originating hardware input events.

This system allows:
* Key bindings to be specified only once when declaring the keymap,
  instead of twice (when handling the events).
* To truly rebind keys in the keymaps dialog. When using traditional
  event mapping, the keymapper remaps the user keypress to the keypress
  expected by the game engine to perform the action. However, the engine
  still accepts the original keys.

The new concept of 'standard actions' defines a set of engine actions
that are commonly available in the games supported by ScummVM. Backends
can define default bindings for the standard actions to hardware
specific input devices.
