commit c09522db1b9f04f96fd57cfc48d7b477bf74bd9c

    Adaptively autocomplete distribution or module names when finding a queue
    
    If the user types a colon, we assume they're looking for a module name
    and switch to mapping modules to distributions via api.metacpan.org.
    
    If the user hasn't yet typed a colon, we preserve the long-standing
    expectation of distribution names and autocomplete against rt.cpan.org
    queue names.
    
    This means that typing "App::Prove" finds you Test-Harness and typing
    "LWP::U" finds you libwww-perl.  It also ensures that typing "libwww"
    autocompletes to libwww-perl for anyone familiar with rt.cpan.org's
    historical expectations.
