PnpUtilGui

Use rcedit.exe from https://github.com/electron/rcedit/pull/180 to avoid a version info corruption

appveyor.yml

Make the window larger by default

Add fallback string resources to prepare for the case that PnPutil.exe.mui is missing / Don't requireAdministrator as it is not needed to just inspect what is there
