Subject: vis-lua: correctly treat return value of input event handler

Returning true from the event handler, indicating that the
keys were consumed, should now prevent insertion as mentioned
in the documentation.

 vis.events.subscribe(vis.events.INPUT, function(key)
 	if key == ' ' then
		-- do something fancy here
 		return true
 	end
 end)
