Merge branch 'Polygon_2-patch_from_a_user-lrineau' 

All Polygon_2::erase() overloads now return an iterator or a circulator,
to make them more convenient (and STL-like).

That patch is a non-significant contribution (as regard the owernship of
code) from a CGAL-discuss user.

Tested in CGAL-4.4.-Ic-91.
