Drag'n'Drop related implementations including:

- dropping MetaContact-s or simple String addresses in the Call dialog would initiate an invite and hence the creation of a conference call or if such already exist just the adding of the new callee to the conference.
- added the possibility to drag the number entered in the call field on the bottom of the contact list.
- replaced previous implementation of Drag'n'Drop in the contact list with the default drag'n'drop mechanism used in java, thus allowing the dropping of contacts outside the contact list (like in an existing call, chat or simply as a string in any other desktop application)
- extended and override the default TransferHandler to provide visual representation of the dragged object (special handling of MetaContacts is provided in the ContactListCellRenderer) and add support of MetaContact flavor.
