Add physics methods to queue and apply movements
Apply movement by queueing it to do later
Improve movement inertia

Handles all 3 axis. Incoming velocity is only added to inertia when
leaving the ground, and does not continually add to it.
Improve mid-air control
Some physics cleanup

Gets rid of some unneeded/unused variables, and halves the 'on ground'
offset.
Implement a jumping state
Fix tracing down
Better handle animations with a 0-length loop
Improve stepping down when starting on the ground
Implement jumping animations
Don't start the jump animation until after the actor is airborn

A bit counter-intuitive, but otherwise certain jump animations will improperly
add an offset to the initial inertia.
Add NPC landing sounds for soundgen keys
Fix a potential divide-by-zero
Deleted old code
New terrain renderer - improvements:

 - Consistent triangle alignment, fixes a noticable crack near the census and excise office. Note that alignment is still not the same as vanilla. Vanilla uses a weird diagonal pattern. I hope there aren't more trouble spots that will force us to replicate vanilla, but at least we can do that now.
 - Fixes several blending issues and cell border seams
 - Fix map render to use the terrain bounding box instead of an arbitrary height
 - Different LODs are now properly connected instead of using skirts
 - Support self shadowing
 - Normals and colors are stored in the vertices instead of a texture, this enables per-vertex lighting which should improve performance, fix compatibility issues due to the PS getting too large and mimic vanilla better
 - Support a fixed function fallback (though the splatting shader usually performs better)
 - Designed for distant land support - test: https://www.youtube.com/watch?v=2wnd9EuPJIY - we can't really enable this yet due to depth precision issues when using a large view distance
Store the object class in the LiveCellRef
Re-introduce lost functionality

The branch merged in 5a863589b4 removed fine-grained configure-time control
over install paths. This is necessary to accomodate various linux distros'
policies, eg. Gentoo wants games installed in /usr/games, but with resource
files in /usr/share/games.

DOCDIR and MANDIR appear to be unused, and were not re-introduced.
cleanup

-   drop trailing slashes from paths for consistency
-   sort entries that got unsorted
Improve actor movement collision handling
Use a better method to do actor physics traces
