Text can only only inside paragraphs and inlines. This patch makes it
so we stop putting such text nodes in the render tree at all if their
parent is not a paragraph or an inline.

This is the final step in making it so that we don't create anonymous
renderers, which fixes a crash in the new custom layout code.

-Make display:flex, flex-direction: column, flex-shrink: 1 the default.
-Simplify StyleAdjuster::adjustStyleForAlignment to remove special cases we
won't need as we make flex the default and remove absolute positioning.
-Fix a bug this exposed in column flexboxes where we'd apply the wrong edge
of border/padding/margin.
-For now leave the default of align-items:stretch. The main change here is
that iframe/img will do width:auto the same as blocks (i.e. the width of
the parent). I think this is a good change, but we'll have to see how it feels
in practice.

When the StocksApp menu is showing, the user shouldn't be able to interact with
the rest of the app. Instead, taps outside the menu should dismiss the menu.

This CL makes that happen by adding a ModalOverlay on top of the app. We might
want to do something fancier in the future using event delegation, but this
works for now.

This CL teaches PopupMenu how to animate out as well as in. Also, I've changed
the PopupMenuItem animations to be driven from the PopupMenu itself, which
makes it easier to run the animation in reverse when closing the menu.

Previously we would spend a lot of time during startup processing all 3k stocks

them incrementally off the network. A future CL will switch to loading them on

It's especially crappy since it doesn't actually do much/any error

Use:

  'sky/examples/terminal/index.sky?url=mojo:netcat?host=localhost%26port=80'

(Note: We don't have a resolver yet, so the host either has to be
"localhost" or an IPv4 address in the form N1.N2.N3.N4.)

Instead of hard-coding the stock data in the Dart file, this CL moves the data
to a JSON file and loads that file over the network. This change improves load
time for the Stocks app from 3 seconds to 2 seconds.

Also, this CL removes shake-to-reload from the Stocks app because that also
slows down load time (due to the two module systems fighting each other).

StockMenu was creating a container for the sole purpose of applying style to
PopupMenu. Now we just use a StyleNode.

Also, I've reverted the change to make box-sizing default to border-box. It
turns out that CL wasn't effective because we didn't use the initialBoxSizing
function to initialize box sizing. I've made us use initialBoxSizing but switch
the default back to content-box because actually using border-box breaks a
bunch of stuff.

This patch adds a new (non-Render) StyleNode which takes two arguments: A (content) node, which it wraps and a Style object.

This allows for styles to be applied to Nodes which are constructed elsewhere (e.g. passed in as arguments).

1) Factors InkWell out of Material so that components can use an ink well
   without needing the shadow/level machinery.

2) Makes the ink effect move at a different velocity once the tap has actually
   occurred, converging with the spec. We don't have the right speeds yet, but
   at least we're approaching the right shape.

3) To support (2), added a primaryPointer attribute to GestureEvents to let
   authors coorelate gesturetapdown events with later gesturetap events.

4) To support (2), modernized SplashAnimation to used AnimatedValue and friends.

5) Added more constants to view-configuration.dart that match Android.

I've also removed the cancelling of the ink effect on scroll. The proper way to
do that is to notice that someone in the event chain is listening for
scrollstart and delay the beginning of the ink effect for some period of time.

This patch removes the mutable API to event handling (Nodes no longer have a events object with which to add listeners).

Instead, a new (non-Render) Node is introduced: EventTarget. This node represents a location in the Effen tree which can handle events as they bubble.

Note that this also changes the implementation to use event delegation (one set of listeners at the sky.document level) rather than direct listeners on leaf nodes.

This CL also refactors how animations work, particularly for the Drawer. I've
renamed DrawerAnimation to DrawerController and switched it from being an
Animation to having an Animation. I've also renamed Animation to AnimatedValue
to capture the idea that the class actually presents the value being animated.
Finally, I've factored AnimatedValueListener out of Drawer so that it can be
used by PopupMenuItem as well.

Finally, I've added a scheduleBuild convienence function to Component instead
of having to call setState(() {}), which has come up a couple times.
