Title: [t2353] initial framebusting protection approach

1. Method to extend Default editor, so new editors do not require large amounts of code to extend TrackEventEditor well.
2. Created webpage-editor.
3. General warning container in trackevent-editor-defaults.
4. Sandbox safety mechanism in popcorn.webpage.js.
5. Added webpage-editor to basic config.
6. Exposed useful layout sources and dom fragments through Editor, TrackEventEditor, DefaultEditor namespaces for easy extension.
