- added a fix in the Gerber parser when adding the geometry in the self.apertures dict for the case that the current aperture is None (Allegro does that)

- finished support for internationalization by adding a set of .po/.mo files for the English language. Unfortunately the final action can be done only when Beta will be out of Beta (no more changes) or when I will decide to stop working on this app.
- changed the tooltip for 'feedrate_rapids' parameter to point out that this parameter is useful only for the Marlin postprocessor
