Exported field_ad_address field into ads_advert module [ADS-56]
Users are now allowed to add adverts to favourites via "Save" link under the advert. Also they have a special page on their profile page "Saved adverts" so they can manage list of saved advert. Also the administrator has ability to view saved adverts for all users via dashboard on /admin/dashboard page
Added "advert preview" image type. Created better advert view experience via "node view" panel's page override [ADS-60]
Merge branch 'master' of https://github.com/mycognitive/ads_features
