GNOME Power Manager 3.11.1 Relies On Intltool 0.50

Thanks to Richard Hughes, GNOME Power Manager 3.11.1 now uses the new 16:9 AppData screenshots, adds copyright information to the AppData file, translates the AppData file, and relies on intltool 0.50 or later for GSettings translation.

Last but not least, the Brazilian Portuguese, Czech, Indonesian, Latvian, Lithuanian, Serbian, Slovenian, and Spanish translations have been updated in this development release of the upcoming GNOME Power Manager 3.12 application for the GNOME 3.12 desktop environment.
