Changeset Bug fix: deletion of groups of external geometry

================================================

Issue reported inter alia here:
http://forum.freecadweb.org/viewtopic.php?f=10&t=12380#p99456

How to reproduce:
1. Make an external geometry hexagon (make a hexagon, pad it, make a sketch on a hexagonal face and make all the lines external geometry)
2. Box select the external lines and press "del"

On the first pressing of "del" 3 lines were deleted and 3 remained, select again, on the second press 1 remains, select again, on the last press all are deleted.

Why?
Internal and External geometry were handled together in a single set. Group deletion of geometry is effected starting from the highest index,
so that upon deleting an element, the index of the remaining elements does not change. Handling both groups together caused that the external geometry
was actually deleted on the inversed order (as they are (decreasing) negative values for representation, but increasing positive indexes in the external geometry array).

Solution:
Internal and External geometries are handled separatedly
