Use the actor's collision shape in findGround()

The cylinder base is no longer appropriate as of the change to capsules.
This also works around a bug when tracing a small cylinder/box shape apparently introduced with bullet 2.86.

Movement solver: add usage of 'on slope' flag to improve handling of steep slopes
...
Previously we were handling 'on slope' synonymously with 'in air' which caused some odd effects.
Practical changes:
- Sliding down a slope no longer applies fall damage.
- Fixed a climbing exploit that would allow climbing steep slopes with repeated use of the Jump function.
