Implements a small language parser to define the emulator events. The event specification is parsed at emulation (when the emulator runs). The ovnidump output now prints the events with the arguments formatted as given in the event description. It also introduces some consistency checks over the event MCVs, which must begin with the model identifier and cannot be duplicated.
