Added basic chat panel - the chat panel show history, timestamp, and nickname (pretty similar to primitivus and wix chat window) - JID has be rewritten to work with pyjamas, and is now in browser_side directory - a widget can now be selected: the message send in uniBox will be sent to it if there is no explicit target prefix ("@something") - a basic status panel is added under the uniBox, but not used yet
