Mockingboard or Phasor cards can be inserted into any slot.
Change Config->Sound to that slots 4+5 to be individually selected for the 3 soundcard types.
Add MockingboardCardManager class to manage multiple cards and mix the sound buffers.
Also:
. support new CpuType independently of Apple2Type
. save-state: don't save disk track image if no disk
. save-state: re-init AppleWin internals & UI to reflect changed Apple2Type
