- Create separate entry for DNS server settings, which can be changed at all times (user is not required to stop the array)
- Added "info" button which shows a popup window with interface related assignments (error is shown if something is missing)
- Added "show" button to show or hide VLAN settings
- Make network settings a tabbed view
- Fixed a bug when sometimes DNS settings are not properly set
- Fixed a minor bug in routing table content
- Some other code optimizations
