Server browser technical and aesthetic improvements
- Retry some servers up to 
nettimeout; consistently reaches a few more servers during my testing - Clear the server list when entering the menu and when refreshing
 - Create a "status line" that displays:
- When the game is checking for an update or loading the server list from the master server (removed the blue message box)
 - How many servers are available and how many the game is trying to contact
 - If there are no servers available (no longer displays below the horizontal line)
 
 - Slide the server list left and right when switching pages
