RemoveTriangle(Int32, Boolean)

Remove a tID from the mesh. Also removes any unreferenced edges after tri is removed. If bRemoveIsolatedVertices is false, then if you remove all tris from a vert, that vert is also removed. If bPreserveManifold, we check that you will not create a bowtie vertex (and return false). If this check is not done, you have to make sure you don't create a bowtie, because other code assumes we don't have bowties, and will not handle it properly
