    Re-add OpenSSL, it's used directly.

    i.e. not through the QtNetwork lib.  We use it for the auto-update
    feature.

    Needed for GLSL code, etc.

    Re-add QtXml to the list of Mac frameworks.

    We're not using the XMLPatterns library, which I disabled in an
    earlier commit, but we are still using QtXml.  QtXml was still
    being built (doesn't seem like we can turn it off in 4.4.3?), just
    not being copied / fixed as a Mac framework.
