Get Indy to properly interact with ledges that start exactly 0.2 units above floor

[thekovic]

This is a quirk of the movement system I noticed while using the level editor. Whenever there's a ledge surface positioned to start exactly 0.2 units above floor height, Indy cannot interact with it properly. A standing vertical jump fails to grab the ledge and a standing forwards jump seems to collide with the seam between the two surfaces. The only way to successfully grab the ledge is a running jump from far enough back. The video below demonstrates the issue:

If this can be fixed, it's a notable change to the game's physics so there should be a way to opt out of it and retain the original behaviour. However, it is a sufficiently jank interaction that I think it's a worthwhile enhancement for regular users (especially if number of custom levels grows).

I've encountered this issue before, and it's definitely something to work on. We need a robust ledge-grabbing mechanic that works seamlessly regardless of the world geometry. I think this glitched behavior might be part of either collision system or sithPlayerActions module (not implemented yet).
