Update pubspec: seems that we already published the package in pub so I'm just
making our version match.

fixes #403, generating a link to a CSS file even if it wasn't generated

Required some refactoring to the order we emit things:
* entry points are processed last
* MainPageEmitter was emitting the entry point as well as doing random HTML rewrites. Now it only does the main dart code. Renamed to EntryPointEmitter.
* Most HTML changes happen in transformMainHtml
* fixed handling of schemes other than HTTP
* removed duplicate code path for rel=components

Factor out renderTests, move TodoMVC tests into example

* all DRT tests now refer to "packages/web_ui/testing/testing.js"
* TodoMVC tests and baselines move to example/todomvc/test
* moved DRT logic from run_all and run.sh into lib/testing/render_test.dart
* the README and build file and pubspec now match editor's copy

The goal here is to get TodoMVC self-contained, so we can run automated tests to validate the sample that ships in the Editor.

Test for TodoMVC editor sample running on drone.io
This means it will show up at https://drone.io/dart-lang/web-ui

My previous change made TodoMVC's tests self-contained. Now I need to copy that into bleeding_edge SVN, and wait for it to get propagated released in a trunk. Until that happens it is treated as a warning if "test/test.dart" is missing.

update changelog for 0.4.2 stuff
update pubspec
remove todomvc pubspec
if it's there, pub won't create packages symlinks which breaks the tests if run from a clean environment (aka drone.io)
