This uses a MouseEventListener and a MouseArea to test whether the
tooltip redirects events, and tests a common implementation scenario
with one shared tooltip.
This test (willingly) exposes a problem that with the MouseArea, we
filter out all mouse events, and the target loses input. I.e. the last
image in the row doesn't receive the click.
KLocale is now kde4support and we have QLocale QML bindings. This patch
removes the KLocale bindings from plasma-framework (they are not used
anywhere anyway).
If we miss something from KLocale in QLocale, we should upstream it.
