figured out how to manually control the fore and aft diveplanes

It's nothing simple, requires some patches to the files to work.
Looks like I also might have found all the ballast tanks for the sub
I need some new icons for the diveplanes for the Officers bar. I need the following:
- icon denoting diveplanes (this when clicked will show the orders bar containing the below):
- icon for manual control of fore diveplanes
- icon for automatic control of fore diveplanes
- icon for manual control of aft diveplanes
- icon for automatic control of aft diveplanes
- icon for fore diveplanes 0 degrees (level)
- icon for aft diveplanes 0 degrees (level)
and any other icons you think will be needed for the diveplanes.
