semion piskarev 8f0627147d MeshModelingTools: Subdivide tool improvements dealing with meshes with open boundaries. ...

- Factor out "extra corner" finding code from PolyEd and add support for it in subdivide tool.
- Add support for rounded corners for mesh boundaries.
- Override subdivision scheme during tool usage rather than just at tool start, to allow extra corners to fix some issues.
- Add some clarifying comments about schemes.
