 - in Geometry Editor - added new information's (length, coordinates and vertex points number) for the geometric element selected in the Geometry Table
 - in Geometry Editor - added more parameters displayed for the geometric elements selected in the Geometry Table: is_valid, is_empty, is_ccw, is_simple, is_ring
 - in Geometry Editor - added a new feature: Simplification. It will greatly reduce the number of vertex points in a geometry element selected in the Geometry Table thus potentially greatly reducing the resulting GCode number of lines
