Deletes: pkg/shadow_dom pkg/custom_element (except web_ui stuff) pkg/html_import Adds: pkg/web_components, with README.md and build instructions Changes: pkg/html5lib -- deprecate queryAll/query in favor of *Selector pkg/polymer -- test fixes & a few small changes to work with new polyfills, mostly in build tests/html/custom -- can't load the CE polyfill at runtime, must now be injected statically via an HTML page, similar to the style @blois used for some custom element tests.
