-control drum will detect the lockable catchblocks now
-rudders in air will now get less drag at higher altitude, up to 35% of normal at 1km above water level

Increased rudder drag in water by about 100%

Controllable drum changes:
-No longer uses grid mass scaling
- 3 different power variants (default should be close to original when grid size is about 250kg)
- inverted variant for each power variant

-You can now dive a lot deeper
-some more fixes to control drum

Some fixes with the controllable drum and made it a bit stronger

NEW BLOCK: Controllable drum

This is a block you can rotate by keybindings. It has various uses, but it was intended to control plane rudders

- small changes to try and get big grids with a lot of subgrids to sleep
What you will notice about this: reduced water bob effect

- Added small sail centered variant
- Tide minimum is saved again
- Performance increase for big servers: subgrids (catchblock) will no longer wake up sleeping grids. This was causing big ships to be constantly awake. Should give a big performance increase on big servers.
