CFRelease CFString objects

Core Foundation functions have names that indicate when you own a returned object:
Object-creation functions that have "Create" embedded in the name;
Object-duplication functions that have "Copy" embedded in the name.
If you own an object, it is your responsibility to relinquish ownership (using CFRelease) when you have finished with it.
