TODO

 * rethink the api and interface
 * markov (with db)
 * match other things than the message itself (maybe just match on e.raw
 * implement launching a script with parameters for "plugins" -> netchan, rpc, jsonrpc, pipe
 * implement users and rights
 * implement commands, and adding commands
 * implement other events than regexp matching (i.e. inactivity on a channel etc..)
  * unlearn
 * parametrise messages, i.e.
     luser: stick: tell eiro he failed
 * strings can't contain escapes: \(, only escaped escapes: \\( which sucks, we need to test also if match is a valid regexp
 * config change: actions is a map now, it should be a slice (or not?)
 * add events: MODE, JOIN, CTCP (action), timeout (not implemented in go-irc-client-library: channel inactivity):
