Fixed the mojo deploy script to no longer deploy mojo.
mojo now uses a more sophisticated CDN, etc.
Fixed old fn.dart to work again. :) Looks like it was
victim of a mass rename.
Fixed engine.cc to be able to handle navigating from
WebView content to SkyView content. We can't handle
the other direction yet, but we don't need to.
/sky_home is written in the .sky system but all of our
new examples are .dart (and thus SkyView).

NOTE: This CL appears far larger than it actually is for two reasons:
1) Many files were moved around to use the Dart package directory structure.
2) Many .dart files had to have import paths updated.
- Organize mojo/public/dart so that it uses standard Dart package layout
- Organize mojo/dart/apptest so that it uses a standard Dart package layout
- Organize sky/sdk so that it uses a standard Dart package layout
- Create a mojo/testing package (used by unittests)
- Introduce the 'dart_pkg' gn rule which populates gen/Config/dart-pkg
- All internally vended Dart packages must have a corresponding dart_pkg rule
- It is now possible to use dependency_overrides: in pubspec.yaml to mix internal and external package dependencies (enables analyzer, editor, webstorm usage for internal developers).
- Package root for dart content handler ends with "packages/"
- Imports of mojo package uris no longer need the "public/dart"
- mojo/public/tools/dart_package.py is a clone of mojo/public/tools/gn/zip.py
- Sky tests no longer run 'deploy_sdk' script.
