This implementation adds the capability to have significant end-user control over GUI customization via skinnable property settings using new skin tags and skin functions. The following functions are included in this implementation: Skin.Toggle-setting(setting), Skin.SetString(string[,value]), Skin.SetBool(setting), Skin.Reset(setting), Skin.ResetSettings. Combined with existing functions like Skin.HasSetting(setting) these functions provide lots of opportunity for new and dynamic GUI customization directly from skin xml. All settings made by a skin are saved into a new file called SkinSetting.xml (lives in the same directory as MediaPortal.xml). Within this file, saved settings are associated with the skin name.
