Add System.Io.Directory class

[morali]

Description

Added Directory class to System.IO.FileSystem library. Directory class API is based on Microsoft one.

Motivation and Context

In order to get rid of two different APIs needed for access to SD Card, I created simple Directory class. It allows for folder manipulation on SD card. For now this API simply calls native firmware methods. It could be used as a starter for developing full featured Directory class.

I am open to any suggestions, as i don't have much experience with developing C# libraries.
