Disable Ubuntu trackers

It's totally useless, put your privacy at risk and might hogs your CPU (usually up to one core)... Citing the official documentation, using bullshit words to describe it:

Tracker is a synergy of technologies that are designed to provide a highly sophisticated, innovative and integrated desktop.

You can't uninstall tracker because the package ubuntu-gnome-desktop itself requires it (believe me, it'll deinstall gnome if you try to do it). Still, you can prevent it from autostarting when you open your session:

for file in `ls /etc/xdg/autostart/tracker*`; do

tracker=$(basename ${file/.desktop//})
