C# Class IrcShark.Extensions.Terminal.History

The History saves a list of typed commands on the console and provides methods to switch through the saved commands.

This code bases on Miguel de Icaza's ([email protected]) LineEditor from the mono project. It was changed to fit the needs of IrcShark and its coding standards.
