- fixed rewrites to properly support @username/outbox, username/outbox, users/username/outbox, ...
- initial support for sending follow to e.g. mastodon (code commented out in api.php)
- database migration for follows table and fedusers table
- save retrieved fedusers in cache and db
- depend more on configs externaldomain, less on server_name
- properly implemented following-logic in dio
- made postForuUser static in newContent and inbox
- provide rsaprivate for signing reuests -> actPub-Servers
- change contenttype depending on use-case
- changed user json-template to have loop-back between user-template and webfinger (mastodon f.e. needs this)
- reworked plugin handling. Main now registers and keeps all connectors and based on request we select the correct one and pass it (mainly for clean async-request-handling)
- added outbox functionality for mastodon
- changed image-mime-type approach to retrieve mime-type from the url, this way we don't need to store the images on our server/download each image
- added host for connector for better debugging
- minor bug-fixes
