- basic code for fake-polygon support (called FGon in code). Disabled now

- hide flags now save correctly in mesh, to restore after going in/out
  editmode
- after an extrude, faces/edges could have wrong select flags
  (only in vertex select mode)
- new rule for addfacelist(); this now copies edges too, if an example
  is provided. That prevents a lot of awkward code, still testing if it
  goes as desired though...
