- fixed issue when loading unbuffered a Gerber file that has negative regions

- fixed Panelize Tool to save the aperture geometries into the panel apertures. Also made the tool faster by removing the buffering at the end of the job
- modified FlatCAMEditor's files to the new string format that will allow easier translations
- updated POT file and the Romanian translation
