QQueue is-a QList, so it inherits the trait that types larger than
a void* cause a heap-allocation when inserted, which is horribly
inefficient.
Use a std::queue instead, which, by default, is backed by std::deque.
Requires rewriting the API calls, since QQueue uses non-standard
function names.
Text and data size increase negligibly (23 and 8 bytes, respectively),
even though we're instantiating a completely new type (std::deque)
instead of QList<QPair<QString, QString>>, which is probably still
used, despite the inefficiency.
