The navigation mesh functionality was broken for quite a while. This patch contains fixes: recalculating tesselations before getting the number of tesselation faces (it otherwise returned 0) before calculating the navmesh, and calling `DM_ensure_tessface()` on the navmesh's `DerivedMesh` object (which fixes visualisation in Blender). This allows one to create a new navmesh, which also works in the BGE. Furthermore, the patch adds several return values, and shows more error messages when things go wrong. In several places in the navmesh creation code, return codes weren't checked and errors silently ignored.
