A display for the base URL with variables highlighter.

Variables after click will be transformed into input elements where the user can enter a value
of the variable. Hosted app should intercept the `uri-parameter-changed` custom event and set
other relevant parts of the application accordingly.

To disable variables editor, set `no-editor` attribute on the element.
