fixed Ports layout, and refactored names in portBlocker.
added onClick methods for udp. tcp and udp ports now go to correct
lists.
opening and blocking the same port no longer adds duplicate entries in
the list. ports now indicate opened/blocked status
Made globals in portBlocker, added a filter menu for ports, added a
colors xml for future use, and filtering now works for open/block/all.
removed unused code
