Second version of the script :D


Very simple GUI only with a button to set all the CPU cores to the
performance governor. This script now does not depends on the the
gnome-applets package (cpufreq-selector).
Most of the functions arent inside de GUI class to allow integration
with other GUIs or already made software.
