- solves the problem of non-standard installs - add AssetPath to config as string var - introduced UiLib constructor which falls back to defaultAssetPath (earlier behaviour) if no assetPath is set - defaultAssetPath now internal concern of UiLib - gui.Start(assetPath) argument passed from ethereal main() as set Init() in config.go - informative log message if wallet.qml fails to open
