It's awkward to work on fn.dart in the examples directory so this CL moves it
to /sky/framework. Also, I've merged the whole library into one file instead of
using the |part| mechanism. The whole thing isn't that big.

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.

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.
