Adjustable step height

This is achieved through removing the Level.HeightUnit const completely and storing geometry height in raw world units as an int. Older prj2 files will have their Y values multiplied by 256 to match original world size. Step height can be switched around using [ ] keys.

ToDo:

• [x] Fix DepthBar
• [x] Add indicator (to indicate whether Precise Mode is ON or OFF)
• [x] Test Room import / export
• [x] Test pathfinding of enemies who can jump / use monkey bars
• [x] Test how precise portals act in older engines
• [x] Adjust rounding for legacy engines
• [x] Find perfect balance for RayTracing rounding
• [x] Test saving prj2 files with complex sectors
• [x] Read through all changes again and make sure everything looks all right

Known issues:

• [x] Slope detection is incorrect
• [x] DepthBar acts weird
• [x] Portal digger uses 1 world unit precision
• [x] Lighting looks different than originally
• [x] Pathfinding of enemies who can jump / use monkey bars is messed up, completely in TR4 and partially in TEN.

It's done and tested! In the future we may allow the user to choose which type of rounding (Default, ToFloor, ToCeiling or Integer) should be used for RayTracing since each one of them makes the lighting look quite different, but for now, this is as close to original as possible.

This was honestly the most painful update I worked on, even more insane than the extra subdivisions stuff.
