- we now check whether the request was sent from contentnation and approve the request with contentnations pub key
- fix issue where inbox wasn't gotten as it also got a username
- rough initial draft of parsing of connector-specific data (plugins/federator/contentnation::jsonToActivity)
- added key paths and headername to config
- 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
