Build 0.77b-p3

Hello again fellow engineers!
A small patch today, mainly to correct a small issue introduced in yesterday's patch, and also an improvement with the colliders for the environment.

Collidable Environment

The environment is now fully collidable, so you will no longer see vehicles mysteriously disappearing and popping out the other side.
Instead, you can do fun stuff like smash vehicles into this pretty mountain:

Bug Fixes

• Fixed issue with checkpoints not triggering correctly when transitioning from a previous level
• Binding key actions to modifers (Ctrl,Alt,etc) is no longer allowed

As always if you find any bugs or have any suggestions please let us know!
Thanks!
