ludic.nav (18.1): a DetourCrowd per kind of walker

Browse source 
The shim builds DetourCrowd from the same pinned Recast & Detour tag. nav_crowd_start puts a crowd on a kind's mesh, with the mesh's tastes as its filters. Walkers are added (snapped to the mesh), sent and sped through verbs, stepped together, and read back into nav_agent_*. nav_crowd_us times the stepping with the OS clock. Dropping a mesh drops its crowd first. On the test meadow, twenty walkers crossing head-on never come closer than their two radii (0.7003 m), all arrive, and a step costs about 12 us. nav 15/15 on the Mac and the PC; the DLL still imports KERNEL32 alone.
