ludic.nav (17.10): the time paths take, counted in the shim

Browse source 
nav_us() gives the microseconds spent in nav_path across the loaded meshes. The shim times each path with the OS's monotonic clock (clock_gettime, or QueryPerformanceCounter from KERNEL32), so the DLL still needs no C++ runtime. Both libraries are rebuilt, and 13 tests pass on the Mac and the PC.
