Added remember plugin to remember quotes from IRC users. This has several

serious flaws:

* Things can be re-remembered. There needs to be safeies on checking for past
  remembered items
* This works across all channels that the bot is enabled in
* This allows users to remember themselves
* Probably something I forgot.
