dln 424cd6bb64 0024774: Convertation of the generic classes to the non-generic. Part 8 
Generic classes:

 "GProp_CGProps",
 "GProp_SGProps",
 "GProp_VGProps",
 "GProp_VGPropsGK",
 "GProp_TFunction" (internal),
 "GProp_UFunction" (internal)

from "GProp" package converted to the non-generic classes and moved to the "BRepGProp" package. Names of several classes were changed to:

 "BRepGProp_Cinert",
 "BRepGProp_Sinert",
 "BRepGProp_Vinert",
 "BRepGProp_VinertGK".

Also all instantiations of the "internal" classes of this classes were moved to the "Geom2dHatch.cdl". For new "BRepGProp_TFunction" and "BRepGProp_UFunction" internal classes two new "*.cdl" files were created.
