Some files are moved by this:
  Copy framework/node.dart into types/ - preparing for framework/'s decomissioning.
  Move app/scheduler.dart into sky/scheduler.dart - "app" doesn't really make sense.

As part of the SkyBinding cleanup, I made the hit-testing less
RenderBox-specific, by having the HitTestEntry.target member be a
HitTestTarget, which is an interface with the handleEvent() function,
which is then implemented by RenderBox. In theory, someone could now
extend hit testing from the RenderBox world into their own tree of
nodes, and take part in all the same dispatch logic automatically.

This involved moving all the hit testing type definitions into a new
sky/hittest.dart file.

Renamed SkyBinding._app to SkyBinding._instance for clarity.

Moved code around in SkyBinding so that related things are together.

Made WidgetSkyBinding use the existing SkyBinding.instance singleton
logic rather than having its own copy.

I also added some stub README.md files that describe dependencies.

Introduce a LeafRenderObjectWrapper abstract class so that RenderObjectWrappers that are leaves don't have to all redundantly assert that they're not misused.

Also, make images use their URL as their src.

Turns out it's ok to not detach all the RenderObjects from the widget
tree from each other, since they're not reused... but the
WidgetToRenderBoxAdapter's renderBox _is_ reused, so we better detach
that one.

The underlying problem is that we lacked a RenderObjectWrapper for the
RenderView, which meant we couldn't handle changing the RenderObject that was
the root of the RenderView. This CL introduces a RenderViewWrapper and uses it
in a new AppContainer widget root. This change allows us to make App a
non-magical Component that is inserted into the AppContainer in the newly
introduced runApp function.
