Add support for remote interaction ([this thing](https://eldritch.cafe/users/Barmaid/remote_follow) in mastodon)
- [x] create the endpoint dispatching remote interactions to local pages
- [x] add this endpoint to web-finger
- [x] propose remote interaction when following and not connected
- [x] propose remote interaction when liking/sharing and not connected
- [x] propose remote interaction when commenting and not connected
- [x] fetch posts/comments we don't know but remote interaction was requested for ?
Also adds a parameter to `md_to_html` to only render inline elements (so that we don't have titles or images in blog descriptions). And moves the delete button for the blog on the edition page.
I still have to update the SQLite migration once others PRs with migrations will be merged.
Also, there will be a problem when you edit a blog while not owning its banner or icon: when validating they will be reset to their default values… I don't see a good solution to this until we have a better way to handle uploads with Rocket (the same is probably happening for articles btw).
And the icon/banner are not federated yet, I don't know if I should add it to this PR or if it can come after?
Fixes#453Fixes#454
* Better contrat for input fields
This change set a white background for input field (text, select and textarea)
to have a better contrast with the page background and improve accessibility for
people with vision problem, and just crappy screen.
This change also remove the round corner for the input to have a clear difference
between editing field and buttons.
This max-width of the form element are a bit bigger too.
* Less space between label and input
This change also remote all units for line-height to have more consistent styles and better cascading support. This solve the too small line height for multi line header in article and also add styling for h1 to h6 (previously h3 to h6 was not styled at all)
