Use named columns if they are available.

Since we can specify complex fields with field_name:column_name, the LinkHandler should recognize those values.

Eg:

  I am viewing a "movie" content:
    | title                     | Test                             |
    | field_movie_facebook:uri     | https://www.facebook.com         |
    | field_movie_facebook:title   | Facebook                         |
    | field_movie_facebook:options |                                  |

I'm not sure how to handle options... Suggestions?

Needs a rebase I think.
