Convert to Qt 5 connect syntax

Convert to new signal/slot syntax where it does not make things more
complicated: connections where the signal or slot is an overloaded
method, or where the receiver method is not in a QObject, are left alone.

The new syntax allows compile-time checking of the connection.
