The after christmas update

I've just uploaded a new update which includes:

• Graphics can now be drafted. If in draft mode a graphic will not be moderated and you can't use it in an ad. If you're happy with the graphic disable draft mode and it will be moderated and you can use it in your ads.
  
• We now calculate the ink coverage of the generated ad. This will likely need to be below a certain percentage to keep in mind the cost of printing.
  
• When uploading a graphic a few cleanup and checks are done on the uploaded pdf.
