REVISION SUMMARY
  When one starts to spin the globe with the mouse (kinetic rotation) and while the kinetic rotation is still being
  processed, setting a new position (e.g. via MarbleWidget::flyTo or via the keyboard, e.g. Home button, etc.)
  two movements interfere: the kinetic rotation of the earth started by the input handler and the second animation via
  the physics timeline done in the presenter.
  
  This patch introduces a new method in the input handler to stop a possible pending earth rotation and
  calls it on the different places needed.

TEST PLAN
  manual testing via mouse and keyboard and with a secondary application which can call flyTo() programmatically

REPOSITORY
  R34 Marble
