Retrieve MemberRef with full Namespace

[th3spis]

    Useful in order to differentiate among different functions with same names, for example:
    - System.Net.Sockets.Socket::Send
    - System.Windows.Forms.SendKeys::Send
    - System.Web.Mail.SmtpMail::Send

    Or different constructors such as:
    - System.IO.Pipes.AnonymousPipeClientStream::ctor
    - System.Security.Cryptography.SHA1Managed::ctor

    It is not very useful to have "ctor" many times in the array returned from get_memberref_names()
