* Fix GCC build.
1) do not fwd declare enums
2) include only base class header file IPropertySheet.
* DSInit(): make sure sound devices are cleaned before the 2nd call.
And use std::string to avoid need of memory management.
This is not complete as header files from Windows/.. are still included in:
Keyboard.cpp
SerialComms.cpp
Joystick.cpp
But probably these are arch specific and will have to be completely reimplemented elsewhere.
. Split AppleWin -> Core with the functionality really needed by the emulator.
. Split AppleWin -> Utilities for generic code not called by other emulator components.
. Split AppleWin -> CmdLine for the command line option parsing.
Changes to ease code compilation in GCC.
Disk_t and HDD contain a std::string and for this reason they need a proper constructor, ZeroMemory is not guaranteed to work.
