* DiscImageChef/Options.cs:

Added currently implemented and in-process of implementing
	  options.

	* DiscImageChef/AssemblyInfo.cs:
	  Completed AssemblyInfo for command line parser to build help
	  upon it.

	* DiscImageChef/DiscImageChef.csproj:
	  Add gsscoder's Command Line Parser Library 1.9.71.2.

	* DiscImageChef/Main.cs:
	  Moved commands to separete functions, use command line
	  parser
