FatRat leaves configs and kills web access

[actionparsnip]

Binary package hint: fatrat

Fatrat uninstallation leaves the proxy defined in /etc/environment. This kills web access as the system looks for a proxy which has now been removed. After taking the lines out which were added by fatrat and rebooting, web connection is ok.

andy@D420:~$ apt-cache policy fatrat

I uninstalled the app, hence "Installed: (none)" but the bug happens. The postrm script should remove the lines to not kill web access.
