Initial commit

Working features:
 - Sending posts from the database
 - Reading posts from the database
 - Responding with MF2-JSON (only in debug mode!)
 - Not locking the database when not needed
 - All database actions are atomic (except for a small race where UIDs
   can clash, but that's not gonna happen often)

TODOs:
 - Send webmentions
 - Send syndication requests
 - Send WebSub notifications
 - Make tombstones for deleted posts (update adding dt-deleted)
 - Rich reply contexts (possibly on the frontend part?)
 - Frontend?
 - Fix UID race

Code maintenance TODOs:
 - Split the database module
 - Finish implementing the in-memory test database
 - Make RedisDatabase unit tests launch their own Redis instances (see
   redis-rs/tests/support/mod.rs for more info)
 - Write more unit-tests!!!
