Implementing SQL

[hackthedev]

Im currently implementing SQL into the entire thing. The goal is to save and fetch messages from the database. Messages created and saved via the file system will still be loaded if sql is enabled. There will be a new section in the config file

I also changed the way media types are detected and how the embeds are created. Depending on the server size and media links posted this can slow down the chat by a lot and because of this i added a media cache thats saved in the database.
