Don't track user specific Xcode files
Cleaned some code that was a but convoluted after conversion to ARC
Changed property name to indicate that we don't want to expose Label objects anymore, we're moving to ORLabel
Don't make legacy labels public but the new labels version using ORLabel instances
Fixed mistake in method implementation
Ensure new instances of ORLabel are not re-created each time labels are requested
Fixed typo in comment
Have sensor registry, maintain it when adding labels and make it available publicly
No need for the SimpleUIConfiguration, getting rid of implementation that gets it.
When retrieving a panel configuration, start the sensor polling for labels update mechanism
Use "normal" call, not SimpleUIDefinition one to retrieve labels to display
