This commit permits to:
- avoid DOM modification when starting options of social_media.
- remove the useless HTML related to the social media block.
- generate all available social networks that are present in the DB for
the social media block.
- delete DB social media if there is no value for it in the DB.
- display an alert banner in edit mode if the block has no link.
- use a shared variable for social media db urls in order to avoid too
much RPC.
- custom links are no longer togglable, only deleteable.
