set jump position in 3d koord

[poppo]

if a map has very complex terrian, or we build elevated-way or bridge, we want to set the jumpping position as koord3d(x,y,height)

I made jump_frame update patch, which we can enter 2d or 3d koord, and jump to there.jump_frame_3d.patchsim.7z 
If input value is 2d, we find the height of the ground.

If input value is 3d, we directry jump to that height (even if there are no ground).


The reason we enable to input no-ground height is to prevent the center point's 2D coordinates from shifting by the height of the ground when taking consecutive screenshots while moving the screen. By taking several shots without shifting the center height, you can easily stitch those screenshots together into a single image.
