Improved Nav Meshes

[pnxenopoulos]

There's a lot of room to algorithmically improve the current navigation meshes

[JanEricNitschke]

Specifically:

• [ ] Consider ladders for connections between areas
• [ ] Connect each area (additionally) to each other area that is within JUMP_DISTANCE and below CURRENT_HEIGHT + JUMP_HEIGHT and has nothing blocking the direct path (raycasting)
• [ ] Take movement restriction into account for distances (times). E.g. crouching through mirage window.
  • Desire/need for crouching seems to be indicated by "dynamic_attribute_flags": 65536. Crouching speed: 85; Running speed: 250.
