Updated crash site /restart command so that guests and regulars can call it when map is cleared

Updated crash site /restart command so that guests and regulars can call it when map is cleared
- Only admin can abort, once the map is cleared.
- Guests and Regular can both call /restart when all enemy units and structures are dead
- Tested on S10 by running this command:
/c local surface=game.player.surface
for key, entity in pairs(surface.find_entities_filtered({force="enemy"})) do
	entity.destroy()
end
- Need to merge into develop to test on live server in case conditions at the end of the game are different
- Thought about adding rocket launched condition but decided against it.
