MacGui: Proposal for replacing UpdateUI timer in HBController. HBCore is a more ObjC-like interface to the core libhb library. It provides notifications of libhb state changes via NSNotificationCenter. Interfaces for scanning, encoding, bindings etc. can be added later. Note: this class is not used in HB (yet).
