woob a11ada4ce2 app: expand functionality of merge-down button 
Adds a number of modifier keys to the layer dockable's new "Merge Down"
button to access further functions, and adds among them a new action to
merge visible layers using the dialog's last values, akin to those
accompanying the New Layer and Add Layer Mask dialogs.

Modifier keys are bound as follows:
  Shift -> Merge layer group
  Ctrl -> Merge visible layers
  Ctrl + Shift -> Merge visible layers from last used values

The Merge Down button is kept sensitive even when the current layer
can't be merged down to allow access to these functions
