Get the game to compile, at least

- Scenario and PC editors still don't link
- Copy files stage set up in the Common project
- Scenario and PC editors now placed in Scenario Editor subfolder in the output directory
- Disabled some totally useless warnings
- "About" menuitem now considered to belong to "Help" menu (even on Mac code) as far as the handlers are concerned
- Dialog string filter is now a function instead of a custom iterator
- Modal session now requires parent window as additional parameter
- Preferences and menus work! Cursors still need some work.
- Since Visual Studio has no way of showing program output that I can find, stdout and stderr are now redirected to a file.
