Subject: [PATCH] infowindow: Pop up infowindow at screen center (#318)

Currently info window will pop up at the topleft corner of the screen,
which is rather bothering. This patch will move the window to
screen center when popped up.

Since QGuiApplication::ScreenAt() is introduced since Qt 5.10, the
code will only take effect when compiled against Qt >= 5.10.
