/// To use, first set the path to your application. For example "C:/Games/MyRPG/"
/// To allow other systems to download files, call AddUploadsFromSubdirectory, where the parameter is a path relative
/// to the path to your application. This includes subdirectories.
/// For example:
/// SetApplicationDirectory("C:/Games/MyRPG/");
/// AddUploadsFromSubdirectory("Mods/Skins/");
/// would allow downloads from
/// "C:/Games/MyRPG/Mods/Skins/*.*" as well as "C:/Games/MyRPG/Mods/Skins/Level1/*.*"
/// It would NOT allow downloads from C:/Games/MyRPG/Levels, nor would it allow downloads from C:/Windows
