There are a couple of Qt classes where you almost always use the
same signal, for example QTimer::timeout, QPushButton::clicked,
and QAction::triggered.
Simply doing timer.connectTo([]{}) is much more convenient, less
tedious and even fun.
Not overloading connect() as it would be confusing to see the
receiver as first argument.
And not naming it onTimeout, as that's a popular way of doing it in
other frameworks. People would assume you could use on* with any signal.
If we ever have on* it should be all or nothing.
[ChangeLog][QtCore] Added QTimer::connectTo(), a shorthand way of
connecting to the timeout() signal.
