Fixed Blockfix files section.
Made NMTDS a no cdl package.
Localization removal.

Removed localization from exchange packages.
Added refactored old occ boolean packages.

In order for geom to work with latest upstream opencascade or oce,
because it had dependencies to old boolean operations classes (which
were removed from version 6.6.0), it was necessary to refactor these
packages (added X in front of class name), and add them back to geom.
Refactored packages for old boolean operations.
Modification for compilation with latest version.

a) New header was added for occ version.
b) Refactored some old boolean operations.
c) Aded GEOM_BaseDriver for sketcher.
d) Updated to the latest sketcher interface.

These changes do not bring in parallel yet the latest upstream geom.
The old geom & geomimpl interface is left back for the moment (TODO).
