[2.x] Add event hook for on_player_super_forced_selected_area

[majoca]

Currently (2.0.11), SelectionToolPrototype allows a mod to specify SelectionModeData for each of the following modes:

• select
• alt_select
• super_forced_select
• reverse_select
• alt_reverse_select

Each of the above has a corresponding on_player_*_selected_area event, except for super_forced_select. Would it be possible to add the missing on_player_super_forced_selected_area event hook? I have a mod with a selection tool that only opens a GUI if the selection is valid, but it makes sense to allow the user to force-open the GUI if they want, and linking this to super_forced_select would be most intuitive.
