chromium_fix.sh added to Kali-Scripts

As the title says, I added a script called chromium_fix.sh to https://github.com/secjohn/kali-scripts.  Chrome won't run as root unless you point it to a different home directory.  Which is annoying on Kali since you run as root.  That change gets blown away every time the package is updated, which is more annoying.  So enter this script.  It will setup chromium to run as root.  Use it every time the package is updated.  I decided to use the Debian package using apt-get install chromium instead of downloading the Chrome deb from Google and installing it, which is what I did for BlackTrack.  So far it is updated far less often so this annoying feature isn't as bad.  If a few people ask for it I'll make a chrome_fix.sh script as well, it is an easy change.  Enjoy.
