This CL changes how events work in fn. Previously, event listeners were passed
in as constructor arguments. Now Nodes hold an |events| object, which contains
all the event registrations. When a Component renders, all its |events| are
copied onto the Node it produces. When an Element syncs, it walks its |events|
and adds them as event listeners on the underlying sky.Element.

The net result of this change is increased flexibility in how events are
registered. Now components don't need to enumerate all the possible events that
they support. Instead, the parent component can listen for whatever events it
likes.

Also, I've cleaned up the association between DrawerAnimation and Drawer. Now
the constructor for Drawer accepts an |animation| object and wires up its
internal event handlers itself instead of requiring the constructor to do all
the wiring.

This CL adds license blocks and cleans up a number of Dart idioms in fn.
Specifically, I've marked several fields as |final| and used Map#putIfAbsent in
some appropriate places.

If there is jank, we might not get a frame time that's just after the last
frame, which means we'll stop generating animation frames before hitting 1.0
exactly.

In this CL, we introduce state to takeWhile to cancel the stream after emitting the
1.0.

This is just a proof of concept. If we like this direction, it will move out of the examples directory (likely re-written) and be committed in smaller pieces with unit tests and formal reviews.

otherwise the new page is sad that the old page took its service provider.

This CL makes the list view in the stocks app more consistent with the material

I removed the green background and added display

I also display a random assortment of stocks every time
instead of always the top 100.

This CL updates sky-box, sky-button, sky-checkbox, sky-input, and sky-radio to
work in Dart. We don't have a data binding system yet, so there's a bit more
plumbing in the code.

This CL adds support for sky-element@attributes, which lets you specify which
attributes your element supports. We use this information to synthesize getters
and setters for those attributes and to dispatch to mumbleChanged methods when
the attributes change.

I've also wrapped the widgets demo itself in a sky-scrollable so the whole
thing scrolls.

After this CL, you can use <sky-element> to describe custom elements. The
current iteration is very basic and is hardcoded to "example", but its a start.

This CL renames the |init| function to |_init| to prevent importers from
calling it directly. Also, we now pass the <script> element to |_init| to give
some context.

These now appear on internals as takeServicesProvidedToEmbedder and
takeServicesProvidedByEmbedder. When you call these functions, you get back the
raw int that represents the handle. We'll need to wrap them up inside the Dart
VM with the appropriate types. We can create a nice wrapper for that in a
future CL.
