Fedi for Pleroma and Mastodon

Aug 16, 2021

Added:
- Soapbox FE brand color support
- PL translation
- Add metadata(description only in this release) support for media attachments. You can view it through media attachments details page and edit them during uploading.
Fixed:
- use background image from frontend_configuration instead of instance metadata for Pleroma until bug will be fixed on Pleroma
Changed:
- Media uploading logic reworked. Media starts upload only after user start sending a message instead of auto-upload on attach
