inside the main roster history (remote stored) should be shown. An interface to retrive the history will provided in near future

Under history there are 4 tabs :

    * Message : Lets user to enter a message inside the bottom text area and update the history
    * Mood : Lets user to enter a new mood status inside the bottom text area and update it using an XMPP message (PEP)
    * Activity : Lets user to update his activity inside the bottom text area and send it to Jabber server using an XMPP message (PEP)
    * Event : Lets user to update current events inside the bottom text area and send it to Jabber server using an XMPP message (PEP)

PEP code should be already inside Joim code or PSI's 0.12 code can be reused
