group vehicles together by type

It's kind of hard to know at a glance how many boat kills I have without looking up each type of boat and then having to add them all together you should list them by attack boat and then riverboat then jet ski et cetera et cetera same for helicopters I think if you group them all together it will make it easier to see how many killers you have with scout helicopters, attack helicopters, boats, transport vehicles, tanks etc.
