FTR: Players should be Realigned Near Box Edges / Stairstepping

[proof88]

It looks nonsense that a player cannot start falling down when only 5% of its body width is on a box, the rest is in the air.
I think in such situation the player should be automatically realigned so it should start falling down.

Btw the automatic stair-stepping should be based on similar logic: when you collide vertically with a wall, we should check the difference of the wall top Y edge and the player's botton Y edge, and if that is within a threshold, the player should be automatically realigned on Y-axis and be let continue the strafing on the box. This way it could easily walk up on the stairs.
