Fixed a couple of issues with unit death messages.
When a unit with a GridNavigator changes cells, the message that is sent now shows the actual elevation of the unit, not the ground level of the cell.
Changed the way the GridManager handles certain message types in an effort to make it cleaner and more robust.
When a unit dies, it now sends its actual elevation in the death message rather than the ground level of its cell.
First pass at implementing breakable pots.
The breakable pot prefab is now linked to the correct model file.

Attempting to have the pots generate a dust cloud particle effect when they are destroyed. The ParticleSystems are causing a crash inside Renderer::addToRenderList
Created some UnitType constants.
GridNavigators can now be blocked by units of specific types.
When performing navigation on the grid, you can optionally choose to ignore cell occupants when pathfinding.
Turned off looping for the pot's particle effect.
Temporarily disabled the particle effect when the pots are destroyed.
