Added unit tests for ORLabel
Added parent class to all widget objects in model
Updated project with settings recommended by Xcode 5 / iOS 7 SDK
Cleaning up some files that should not be under version control
Enabled modules support (requires Xcode 5)
Added unit tests for ORWidget
ORLabel now inherits from ORWidget, so we can have an appropriate hierarchy for widgets in the object model
Change ORLabel init method to take id, now that it inherits from ORWidget
Don't use ControllerProxy / ORControllerPanelsFetcher but directly use ORController from client library to get list of panel identities
