WebContent+Friends: Add IPC and plumbing for WebDriver endpoint

Browse source 
To use the `GET /session/{id}/element/{id}/css/{property name}`
WebDriver endpoint, two new IPC calls through the Browser are
implemented:
    - get_active_documents_type returns the type of the active document,
      which is either "xml" or "html"
    - get_computed_value_for_element returns the computed CSS value (as
      String) for the given element and CSS property name
