Comment 8 for bug 1307002

Have got the goahead to do this - I have attached my current WIP patch on this, feels like a hack but its worked for one attempt so far - playing with Bulk Rename, I removed 'Utility -> Accessories' and it disappeared from Accessories which is great, however when I tried to add the 'Utility -> Accessories' category back via System entry, I found there wasn't an 'Accessories' option under 'Utility'.

The options are sourced from MenulibreAplication.py:category_groups - is there any logic to what is and isn't here? Can I add any missing categories so that they match up with normal categories present on launchers?
