Hi all,

Here's a few more refinements to the powertrain updates on the experimental branch. Did a big stabilization pass in this one too.

Additions

• The driver will now attempt a hill start on inclinations greater than 5 degrees. This should let you get going again after braking to a halt on a slope.
The RPM the driver will go to before entering 1st gear will increase up to the upshift RPM as the inclination increases.
• Added undo-redo support for the engine and transmission designers. This also works when loading individual engine/transmission blueprints.
• Undo/redo now logs which action was undone/redone.

Changes

• Increased engine torque at lower RPMs.
• Adjusted wheel collisions to be closer to the centre of all wheels on an axle, instead of at the suspension connection point.
• Renamed engine design RPM property from 'Max RPM' to 'Safe limit'.
• Reimplemented engine RPM limiter design, should be less janky now.
• Made the Unity logo splash screen background fully black.

Fixes

• Fixed turrets being considered [Not Connected] when placed on the central seam of a compartment split down the middle (like a pike-nose).
• Ensured no designer processes are running outside of the designer. Was resulting in the ability to move track wheels in photomode.
• The track belt now disappears correctly when there are no roadwheels in the track.
• You can no longer exit the designer without any roadwheels.
• Power preview in the engine designer now takes the torque curve into account.
• Cruise control now resets when returning to the designer.
• Fixed custom battle team setup save & load GUI not automatically disappearing when leaving the custom battle screen.
• Roadwheel spacing slider no longer displayed with interleaved wheels, as it didn't do anything.
• Fixed cannon balancing tip being partially cutoff.

File-editing notes:
Numbers are no longer clamped when loaded from a blueprint. This makes things simpler on my end and lets you see file-edited figures in-game.
