removed obsolete import
added 'ScaleMode' to 'RectangleUtil.fit' method

Which makes this method a worthy replacement of 'stage.scaleMode'!
updated 'stop' method documenation
removed 'isMac' check, annoying when testing context loss ;-)
reverted recent change of Starling's 'contextData' vs. 'customData' property (refs #218)

This caused more trouble than it's worth. The combination of allowing a shared context as well as automatically handling a context loss is difficult to balance.
using 'pixelPerfect' viewPort scaling only on iOS
refactoring once more: re-added contextData, but now it's bound to the stage3D instance

That way, the context data survives a context loss, and we've got the best of both worlds.
Actually, I had prefered 'Starling.instanceData', but to make that work when two Starling instances share the same context AND need to handle a context loss -- would have required Starling to be able to dispatch weak events (which is not possible ATM). Otherwise, memory issues would pop up if poeple forget to call 'dispose' on their display objects. Long story ...
