- Port State (Link/Transmit/Capture) now updated alongwith port stats
    - On link state change, the port window is not updated - partial changes have been done under #if 0; needs refactoring of Port Class implementation/usage before a signal/slot for the same can be implemented

Fixes
  - Fixed crash in client when connection to server is broken
  - Packet Capture and Capture Buffer Retrieval now works correctly and consistently (I think!)

Others
  - Minor visual changes in Ports Window
  - Port Stats Window now has 'right' alignment for stats data and 'center' for state data
