MaxED 4abcca3cf8 Fixed incorrect behavior when sector had 2 or less sidedefs after vertices or linedefs removal.
Fixed incorrect behavior when 2 linedefs are merged into one after deleting a vertex, when a newly created linedef overlaps existing geometry.
Visual Vertex handles were not updated when sector's floor or ceiling height was changed.
