prepare release

• supergfxctl 3 support: Changed nvidia to dedicated, corrected acl arrays, updated icon names and readme (thanks to @DualityKyle)

• GPU icon in panel now in sync again with the current mode if changed

• Profile icon in panel is now in sync with Power Profiles Daemon

  • therefore anime and battery clients won't get started if not supported and won't show up in the menu

• AniMe Matrix brightness slider added

• All log entries now use the Log.debug function (except errors and warnings) + a variable that enables the logging (we still need to make a preference out of it) - this is necessary for a official release

• Simple preferences dialog

  • notifications on / off
  • debug messages on / off (requires reload of gex at the moment)

• Updated gschemas for the current preferences

• Updated Power Profiles Daemon DBUS introspect XML

• Updated Power Profiles Daemon DBUS client to listen to the PropertiesChanged signal

• Added asusd support DBUS introspect XML

• Updated README.md for more clear installation instructions

• Updated screenshots

• Updated install script

  • checks if the extension was installed before
    • if not echoes it echoes instructions to restart / logout and -in again
