cpupower-gui 1.0.0

pyxdg is now a required dependency along with libhandy

Highlights:

• Added Italian translation
• Redesigned the GUI using libhandy and now it is mobile friendly too.
• Add extra preferences along with a preferences page to control the GUI.
• The GUI stores its configuration in ~/.config/cpupower_gui/00-cpg.conf.
  This way you can have files that override the default behaviour, but being able to change the settings at runtime without persistence.
• Refactored the command line option and now it supports more subcommands.
