Properly use detail mesh from closestPointOnPoly (#228)

Browse Source 
When a point is outside the polygon being queried in
dtNavMesh::closestPointOnPoly and dtNavMeshQuery::closestPoinOnPoly,
Detour will interpolate along one of the edges to find the closest point
on the poly. However, Detour did not properly use the interpolated point
to find the correct height according to the detail mesh.

Fix #227
