Change data off singal icon

I have had this request a few times... and it is ambigous if it is off or simply no signal

PS3 - rewrite - still in testing
PS4 - syntaxeses.... nuke do I even need to state !(rssiState.dataTypeIconId > 0), it should be inferred by first condition
PS5 - SyNtAxEsEsEsEsEsESEs
PS6 - Add helper function to QuickSettingsModel to diferentiate connectivity and enablementhoodness.
