Documentation: Show an example for each overloaded signal

The new connection syntax is a bit tricky to use, when the signal or
the slot is overloaded, because one must explicitly cast to the
correct signal type.

This patch adds an example to the documentation of each overloaded
signal. The example shows how to do the cast to the correct signal
type.
