This commit fixes the button label overlapping over the button borders
when the button height is manually set to a value bigger than the
icon's smallsize.
Review done by notmart on IRC.
MouseEventListener listens to both child events and events passing
through itself; child events are recorded so the handler for the
latter can perform a comparison and avoid emitting signals for the
same event again. However, this comparison could fail because the
member used to record the last child event would also be updated
for events we were not actually interested in.
A real-world example of this is opening a popup menu in repsonse to
a Press event. This causes an Ungrab event on the child, which would
cause the comparison to fail and mousePressEvent to announce the same
press yet again.

Property windowId was according to the comments only provided because
KWin needed it. KWin's usecase was to know the window Id of the window
where a given item is rendered to. In QtQuick a QQuickItem provides a
pointer to the QQuickWindow holding the item. This means this hack is no
longer needed.

The implementation now specifically tries to support byte arrays
being passed in, which is what the base class speaks. To try and
retain the previous behavior anything else is attempted to be
converted to a string and failing that, silently dropped.

both the applet and its compact representation can now export minimumWidth,implicitWidth etc and those are exported to the root graphics item.
the minimum width of the applet is used to collapse in popup
emit click if the cursor is still in the area regardless of the
distance travelled
this because MouseEventListener doesn't start drags
