small fix for bad column data
Experimental changes to AisTableModel and AisDialog to make use of a queue system which
should make the gui more responsive since updates happen in a seperate
thread. May neeed to reconsider fireTableRowsUpdated/fireTableDataChanged
which do not happen in the event dispatch thread, atm.
Workaround to always draw metoc data properly (need gui scale fix)
changed from ArrayList to LinkedList to improve memory usage
