qDebug() replaces newlines with \n unless called with .noquote()

Previously, when QString containing newline characters was fed into qDebug() using the << operator, qDebug would print that string and make a newline in stderr everywhere where a newline character was in that string.

Now it just prints "\n", unless you append ".noquote()".

This forces anyone who used qDebug to output QStrings with multiline error descriptions to run through the codebase and replace qDebug() calls with qDebug().noquote().
