Add exploit for TrueOnline Billion 5200W-T

[pedrib]

    TrueOnline is a major ISP in Thailand, and it distributes a customised version of
    the Billion 5200W-T router. This customised version has at least two command injection
    vulnerabilities, one authenticated and one unauthenticated, on different firmware versions.
    This module will attempt to exploit the unauthenticated injection first, and if that fails,
    it will attempt to exploit the authenticated injection.
    This module was tested in an emulated environment, as the author doesn't have access to the
    Thai router any more.
