Fixes: NB#182815 - Pannable widget is not transparent wrt. passing focus to child widgets

RevBy: Jarno Malmari, Michael Hasselmann, Dominik Kapusta
ModifiedBy: Dominik

Details: This patch completely removes mouse event replaying functionality
in the pannable widget and moves necessary pieces to mscene. This should allow
better focus handling in the scene and also should remove all crashes related
to mouse event being bounced between pannable widgets when two of them are
placed on the scene.

Modifications: Provide MScenePrivate::init() and rename
MScenePrivate::sentCancel to cancelSent.
