Support different agent collision shape type for pathfinding Actors may have different collision shapes. Currently there are axis-aligned bounding boxes and rotating bounding boxes. With AABB it's required to use bounding cylinder for navmesh agent to avoid providing paths where actor can't pass. But for rotating bounding boxes cylinder with diameter equal to the front face width should be used to not reduce of available paths. For example rats have rotating bounding box as collision shape because of the difference between front and side faces width. * Add agent bounds to navmesh tile db cache key. This is required to distinguish tiles for agents with different bounds. * Increase navmesh version because navmesh tile db cache key and data has changed. * Move navmesh version to the code to avoid misconfiguration by users. * Fix all places where wrong half extents were used for pathfinding.

void updateBounds(const osg::Vec3f& playerPosition, const UpdateGuard* guard) override;
Cull navmesh objects by scene bounds If object is too big iteration over all tiles covering it can take too much time. Limit bounds to a square around a player position to cover only tiles that will be present in navmesh based on max tiles number option. Each object is associated with a set of tiles its present in. Culling can reduce this set but it has to be update when bounds change position. Do this in TileCachedRecastMeshManager::setBounds updating the set and adding/removing objects to the corresponding CachedRecastMeshManagers.

Build limited path for far destinations When distance between start and end point is greater than max radius of area possibly covered by navmesh there is no way to find path via navmesh. Also if distance is greater than cell size navmesh might not exists withing mentioned area because cell is not loaded therefore navmesh is not generated. So minumum of these values is used to limit max path distance. Assuming that path actually exists it's possible to build path to the edge of a circle. When actor reaches initial edge path is built further. However it will not be optimal.
