TODO
- fix bug: not saving existing .zip after a Collect for Output is run
     this bug occurs because after running an effect extention the inkscape:output_extension is reset to svg.inkscape
     the file name is still xxx.zip. after saving again the file xxx.zip is written with a plain .svg which 
     looks like a corrupt zip
- maybe add better extention
