Initial attempt to get display traits working with ASEnvironment.
To get proper ASDisplayTraits support, you must use an ASViewController. The ASViewController implements UITraitCollection-related methods (`traitCollectionDidChange:`, `willTransitionToTraitCollection:withTransitionCoordinator:`, viewWillTransitionToSize:withTransitionCoordinator`) to update the internal ASDisplayTraits and propagate them to subnodes.
ASTableNode and ASCollectionNode don't actually have their cells as subnodes, so a little bit of trickery is involved (on `setEnvironment:` the table/collection node gets its data controllers completedNodes and propagates the new traits. see `ASDisplayTraitsCollectionTableSetEnvironmentState`). The data controller also passes the current display traits when creating new cells.
ASViewController also supports the ability to return a custom set of display traits. So if you have a modal dialog that should always be told it is in a compact size class, you can set the override block before displaying the VC.
A new example, called Display Traits, has been added. It shows how display traits can be used in a ASViewController with a normal ASDisplayNode as its root, as well as in ASViewControllers hosting table nodes and collection nodes. There is also an example of overriding the default display traits of a VC.
Please provide feedback!
* changed static string to ASVideoPlayerNodeControlType
* public property for duration
* public method for seek
* new _controlFlexGrowSpacerSpec; used to use flexible space in
controlbar. for example if user does not want to have scrubber, he can
replace it with flexible spacer and duration text node will be kept at
the right edge.
Summary: Previously the first thing we did when calculating the size of text was to truncate it. This could lead to ASFontSizeAdjuster being sent a truncated string which, obviously, never needed to shrink. If we change the order then we first shrink, then truncate if still necessary.
