The earlier approach of loading `/api/config.js` as a script on
initial page load with the necessary variables to init the UI is
ditched. Instead, it's now `/api/config` and `/api/settings` like
all other API calls. On load of the frontend, these two resources
are fetched and the frontend is initialised.
This is a major feature that builds upon the `Messenger` interface
that has been in listmonk since its inception (with SMTP as the only
messenger). This commit introduces a new Messenger implementation, an
HTTP "postback", that can post campaign messages as a standard JSON
payload to arbitrary HTTP servers. These servers can in turn push them
to FCM, SMS, or any or any such upstream, enabling listmonk to be a
generic campaign messenger for any type of communication, not just
e-mails.
Postback HTTP endpoints can be defined in settings and they can be
selected on campaigns.

- Override glitchy Buefy animations (sidebar, toast etc.)
- Fix tag alignment inside tables in responsive view.

- Miscellaneous styling fixes.
- Add missing Fontello icons.
- antd+react was resulting in extremely clunky and unreadable
spaghetti frontend code (primarily due to how antd is).
- Buefy is lighter by an order of magnitude, has excellent
responsive views (especially tables) and usability.
- Vue's templating produces far more readable template code.
