Add Server Separation in Bot Loader

[bdbch]

First we need to check all connected servers when the bot is connected here: https://github.com/Devcord/cordlr-cli/blob/4624e2951136dc8420d415473f5be5f929ceea20/bin/bot/index.js#L25

For each server connected, we need to check if the server is already "registered" in our database/storage, if not add it to the set of data.

Here we need to add a check and specification for the server of the incoming message. Maybe we also allow direct messages while we're at it since they are now disabled. Lets do this in another issue.

When the message is handled, we need to pass the server ID into the plugin command so the plugin can work with different servers, load different configurations per server, etc. etc.
