Internal and external documentation updates needed

There is some documentation (internal javadoc and external) that has not been updated to reflect the changes between 2.0 and 3.0.
E.g. (Internal)
org.jivesoftware.smack.XMPPConnection
javadocs out of date
/**

• // Start a new conversation with John Doe and send him a message.

• Chat chat = con.createChat("jdoe@jabber.org"); <---- no longer able to do this

• chat.sendMessage("Hey, how's it going?");
  ...
  */

(External) in smack/trunk/documentation/overview.html

XMPPConnection connection = new XMPPConnection("jabber.org");
connection.login("mtucker", "password");
connection.createChat("jsmith@jivesoftware.com").sendMessage("Howdy!"); <---- no longer able to do this
