Prior to Qt Quick Components 2.1 there was no onPressed signal for a
TextField; in order to be able to build against Qt 5.7 (which comes with
Qt Quick Components 2.0) we need to work around the lack of this signal.
This code seems to do a pretty good job at simulating it.
My attempt in commit 73c66e1d7d ("QML UI: make run with Qt 5.7 again")
didn't work so well.
