Made a few tweaks after using WirePeep at work for a bit:
- Added resize grip to status bar.
- Made default splitter position be 80/20 instead of 50/50.
- Made "Start Minimized" option only apply to "Run when user logs in".
- Added option to confirm closing the app (automatically confirmed by Windows logoff or shutdown).
- Added Unselect commands to right-click menus.
- Added current release link and build badges to readme.
- Fixed a bug where two entries with the same group name and location name couldn't be compared by address (since IPAddress doesn't implement IComparable).
