	* Environment.cs: Implemented OSVersion property.

	* Path.cs (GetDirectoryName): Fix for filenames with size = 1

	* File.cs: Removed all references that threw exceptions when the
	paths contains a colon, as this is a valid part of an identifier
	on Unix.

	Everywhere: The String.Empty return from GetDirectoryName means
	that there is no directory information about the path.
