Added ArrayList for PersonChangedListener
Removed: DB Write Connection for SearchPanel no longer required
personChanged(Person): Needs to send XMPP to trigger change on server
Whitespace Edit (yes I know but it was bugging me)

This may cause unacceptable remote delays, need to test once complete.
Thread to remove listeners from the SearchPanel.  Used upon completion
to not reference old objects that don't exist
