Mac v6 beta test

[Admins]

Big release for Mac. Beside the new RC there is also v5.306:
- Uses fonts from the system folder, which means less downloads, more choice for the default font. Some fonts will look slightly different, eventually we will replace them sometime.
- The default keys (escape, F1 etc.) have been reworked and now use script. There are new events onControlKeyDown/Up with parameters keycode,keytext,scancode and window name. Closing the default external windows with escape key should work much better now. Pressing Escape in the main game window will show a scripted external window now for the quit dialog. We will be able to change this behaviour by script.
- Filebrowser enhancement: in the scripted RC you can now double-click on files to open the file in the default viewer or editor
- New location for downloaded files: Everything goes into ~/Library/Application Support/Graal. It will not share the data with v5 (except if you create a dynamic link to the old folder). So it will be easier to access screenshots etc.
- The game is not scanning the current directory anymore, so you can easily place Graal.app into your Application folder like any normal application.
- Supports playback of ogg files (sound effects on Era)

Part of the reason for these updates is that we want to make Graal (and the engine) ready for the Mac App Store. If you find any problems then we will quickly fix them.
