    MoinMoin - FarmFullSearch Macro

    [[FarmFullSearch]]
        displays a search dialog, as it always did.

    [[FarmFullSearch(Help)]]
        embeds a search result into a page, as if you entered
        'Help' into the search box.

    Changes:
    * 2006-11-18 (DavidLinke) Handle failure of xmlrpc request gracefully
                 Failure is expected e.g. when authentication is required.
