World of Diving: UI depth, convergence, shadows + misc ini changes

- Get the MVP and MV matrix from the lighting shader again. This seems
  to work pretty reliably in game, just not on the menu where only
  directional shadows are used. May still have to play through a few
  parts of the game to see if there is any other areas where neither of
  these shaders are used.

- 1-4 are used in the game for hand gestures, so only use 5,6,7,8,9,0
  for UI depth adjustment.

- Split convergence presets into two keys:
  - [ sets 0.03 - a conservative value that puts everything behind the mask
  - ] sets 0.1 - some things in front of the mask, but the 3D effect is
    much better
