Event on_selection_changed request

[jonatkins]

There's a "selected" property in LuaPlayer (actually LuaControl), but, as far as I can tell, no event fires when this changes.

Perhaps add an on_selected_changed event, with event parameters specifying

• the player
• the newly selected item (or nil if deselecting)
• the previously selected item (or nil if not set)

This event would fire a bazillion times per game, though, possibly leading to bloat due to needing to log every event...

[jonatkins]

Logging every event? You mean with replays enabled?

Anyway, the data might already be recorded - to update the state of player.selected property.

For now, in my mod, I've added code to monitor for changes to player.selected in on_tick - so it's already possible, but a little ugly and inefficient compared to a dedicated event.

The event could potentially be despammed - so that a selection must persist for 500ms or 750ms before the event is fired.

It will certainly be less crufty than having a bunch of mods checking the selection state of all players via on_tick handlers.
