Problem: the old test suite was extremely inflexible
This meant that making new tests took way too much time.
+ This new rework makes the new client's backend much thinner and less "magical"
With less magic going on we can pass way more data more easily to the actual
http-request engine making the convenience wrapper over top it much more flexible
Translating old tests to the new engine might take a while but for now the old
client codebase is completely deprecated and will no longer be used+updated
➕ Moving Messages struct in db-lib to root for less namespacing uglyness
➖ Removing an whole unused trait
✨ Message::get_time_range now returns a special 'UserMessage' struct that includes the name of the author
❗ More code must be removed from db-lib since a ton of the trait methods aren't used anymore
* payloads for things like /message/send are now send through the request body
* no longer sending body data in gets
This whole patch is basically so we can allow js clients to exist btw -_-
