Add policy to Polkit

http://www.webupd8.org/2015/03/how-to-run-gedit-and-nautilus-as-root.html

Add the file https://raw.githubusercontent.com/hotice/webupd8/master/org.gnome.gedit.policy
to /usr/share/polkit-1/actions/

So the user can start a gedit session with superuser privileges to edit files outside the home directory using 'pkexec gedit'.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Thank you for reporting this bug to Ubuntu.
Ubuntu 15.10 (wily) reached end-of-life on July 28, 2016.

See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed.

There is still no easy way to edit files that need root, example files in /etc/ in gedit.
Even as of gedit 3.30.1.
