New Pull Request

Hello Sir,
This branch I forked so I add some stuff that will not be suitable via patches so please Merge with Master
you need first to install a package named "xautomation" to make refresh WORK
this revision adds:
 1. ability to clear emblem / icon
 2. ability to set emblem/icon
 3. lots of icons

If you accepted the pull request I can go on and make Ubuntu PPA for your extension or if you agree 
i can add it to nautilus-actions-extra pack :)

please if you have new Ideas please tell me
Happy to share work with you
