WebDriver: Add POST /session/{id}/element endpoint

Browse source 
This allows you to query for elements in the active document!
The IDs of matching elements are returned through the WebDriver
interface, for now there's nothing to do with this information.

This introduces a `LocalElement` to the Session, which for now only
holds the ID of a real browser-side element. Once more data of elements
are available to the Session, they can be stored alongside in this
struct.

Fixme's introduced are:
    - Only CSS selector location strategy is implemented for now
    - `get_or_create_a_web_element_reference` returns the elements ID
      instead of a UUID generated in a spec way.
