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.
for MWWorld::Action, ProjectileManager and ESSImport::Converter.
shared_ptr has additional cost of reference counter and requires additional
allocation when constructed as shared_ptr<T>(new T).
Even when target is not reachable actor will try to run there either because
target navmesh polygon is selected within extended area or because partial path
is built to the closest possible polygon.

This allows to distribute AI reaction calls over time.
Before this change actors appearing at the same frame will react in the same
frame over and over because AI reaction period is constant. It creates a
non-uniform CPU usage over frames. If a single frame has too many AI reactions
it may cause stuttering when there are too many actors on a scene for current
system.
Another concern is a synchronization of actions between creatures and NPC.
They start to go or hit at the same frame that is unnatural.
1. Move weapon types behaviour from switches to the table (should allow
us to de-hardcode weapon types later)
2. Gereralize bones injection to actors skeletons (instead of using the
hardcoded xbase_anim_sh.nif)
By definition this is not 'Mutable state of a cell' and does not belong in CellStore.
This change should improve startup times (graph is now loaded on demand) and edits to 'pathgrid.hpp' no longer cause the entirety of OpenMW to be rebuilt.
