Update device configuration from gnome-settings-daemon
GsdWacomDevice has been updated, dragging GsdDeviceManager as a dependency from g-s-d, which has been added to panels/common, and compiled as a separate static libary, which is used by the wacom and mouse modules. gsd-input-helper.[ch] is now in such library and has been removed from the panel directories. https://bugzilla.gnome.org/show_bug.cgi?id=743196
