Ugs - Updated ugs to read the configuration via the shared library, thus removing the support to read it from UnrealGameSync.ini. Added a ini setting to allow which providers to use though, so that we can have more providers listed in the configuration then UGS will want to care about but also to allow us to control opt in of this feature per project.
