unit UPlatformMacOSX;

Note on directories (by eddie):
We use subfolders of the application directory on tha mac, because:
1. Installation on the mac works as follows: Extract and copy an application
and if you don't like or need the application anymore you move the folder
to the trash - and you're done.
2. If we would use subfolders of the home directory we would have to spread our
files to many directories - these directories are defined by Apple, but the
average user doesn't know them, beacuse he or she doesn't need to know them.
But for UltraStar the user must at least know the songs directory...
Creating a subfolder directly under the home directory is not acceptable.
More on this from KMS aka mischi
Handling of resources and folders should follow these lines.
Acceptable places for files are folders named UltraStarDeluxe either in
/Library/Application Support/
or
~/Library/Application Support/
Then
GetGameSharedPath could return
/Library/Application Support/UltraStarDeluxe/Resources/
GetGameUserPath could return
~/Library/Application Support/UltraStarDeluxe/Resources/
USDX checks, whether GetGameUserPath exists. If not, USDX creates its.
The existance of needed files is then checked and if a file is missing
it is copied to there from within the Resources folder in the Application
bundle, which contains the default files. USDX should not delete files or
folders in Application Support/UltraStarDeluxe automatically or without
user confirmation.
