* Removed Samples button and dialogue.
* Removed SoloMesh.
* Removed TempObstacles.
* Limit 'Verts Per Poly' to 6 (DT_VERTS_PER_POLYGON).
* Moved hulldef constant and handler to TileMesh.
* Set m_tileSize based on hull (small = 32, med_short = 32, medium = 32, large = 64, extra_large = 64).
* Add missing dtQueryFilter field (some flag used in the engine but not sure yet what it does).
* Set tile->polysEnd and tile->offMeshConsEnd to end of polys and offMeshCons array pointer (if ever needed).
* Set camera perspective to 75 (previous 50).
* Improve theme.
* Lowered the climb height for all hulls (this improves NavMesh generation around low obstacles, previously it would create a poly connecting the ground on the side with the surface of the object around where it connects with the ground, causing AI to take this route instead and kind of 'glitch' onto the surface).
