Implement isExposed() for UbuntuWindow and store visible state passed in via handleSurfaceVisibleChange().

272. By Mirco Müller on 2015-07-23

Use better-fitting term of "exposed" instead of "visible" in related calls... also matches qtmir's meaning of visibility better.

273. By Mirco Müller on 2015-07-30

Use temp. logging for UbuntuInput::customEvent().

Make a client-window set its visible-flag based on corresponding mir-surface-event coming in.
