Private chat enhancements

[HairyFotr]

Currently it's a quite basic ELIZA chat.

Enable memory for things people have said (done in standalone but commented out here)

Refactor and add more parsing rules

Try including some WordNet, statistical answers, jokes, etc.

Add features from the channel chat.
