* Check if server is active in command callback before attempting to hot swap.
* Hook 'v_Detour_LevelInit', and log NavMeshes that failed to load.
* Split free/destroy logic into separate function.
* Created constants for NavMesh and AI Network paths/extensions.
* Added performance profiler for hot swap logic in command callback.
* Renamed "navmesh_reload" to "navmesh_hotswap".
* "navmesh_hotswap" is now development only.
The new command 'navmesh_reload' hot swaps the current NavMesh for all hulls in memory, with that of the 'new' files on the disk. The memory of the old NavMesh gets freed and destroyed.
The reachability table needs to be figured out still. The issue should be very small, but at the moment I do not have time for it.
The pointer to the table, and table pointers to data is correct, however, not a single poly is ever getting marked as 'reachable' (0xffffffff). This could be either within recast itself (see build_link_table() and set_reachable() functions), or the way the engine parses the data. The function that determines whether poly is reachable is located at '0x140F448E0'
