Update invite hook to use irc_paramlist instead of paramlist
Add some type documentation to a few plugins
Fix bot types on correction and encrypt plugin documentation
Add logging config and move logging config options to it
Rename event.irc_message to event.content
Only set event.context if the command is PRIVMSG. This allows for checking if an event is a message without relying on irc_* params, and anyways plugins can use event.irc_paramlist[-1] if they want the last param for non-message events.
Merge IRCConnection into BotConnection
Split BotConnection into an abstract Connection, and an implementation IrcConnection.

Also:
- Change realname to point to cloudbot.pw
- Fix QUIT messages not being displayed when being killed
- Change conn.cmd(name, [arg1, arg2]) to conn.cmd(name, arg1, arg2)
- Add conn.action and conn.notice for non-irc-specific action/notices
Add profiling plugin for debugging
