Need declarative lazy imports for views, otherwise they look like undefined custom elements

[rictic]

i.e. in polymer-1-app/src/my-app.html there's

          <basic-view name="basic-view"></basic-view>
          <content-view name="content-view"></content-view>
          <name-view name="name-view"></name-view>
          <shadowdom-v0-styles-view name="shadowdom-v0-styles-view"></shadowdom-v0-styles-view>
          <polymer-dom-view name="polymer-dom-view"></polymer-dom-view>
          <not-found-view name="not-found-view"></not-found-view>

But these elements look like they're undefined, and the linter says so. Solutions in descending order of niceness:

• Add lazy imports to the source, make the analyzer/linter understand them
• Teach the linter to ignore a warning for a range of source
• Use the ignore clause of polymer.json to ignore undefined element warnings entirely.
