Fixing TransitionEnd event.

Fixing TransitionEnd event.

A number of related changes-

Bug 8340 is that we previously had WebKitTransitionEnd renamed to TransitionEnd, but had to remove that when Chrome added a new TransitionEnd.

Changes-
- Made WebKitTransitionEnd implement TransitionEnd and made it private.
- Added a test for the TransitionEnd event.
- Fixed the TransitionEnd event not working on non-Chrome browsers.
- Added support check for CSS transitions.
- Added annotations for CSS transition support.

lgtm, but I think we should move one of these files into a separate CL (see
comment)

https://codereview.chromium.org/12211099/diff/1/tools/testing/dart/http_serve...
File tools/testing/dart/http_server.dart (right):

https://codereview.chromium.org/12211099/diff/1/tools/testing/dart/http_serve...
tools/testing/dart/http_server.dart:48:
TestingServerRunner.startHttpServer('0.0.0.0',
Can we put this in a separate CL that has Martin or Peter or someone cc'd on?
Also, we should add a comment explaining what 0.0.0.0 actually does for those
who didn't take time to read the source code. Also, we should probably file a
bug on dart IO asking them to document that! :-)
