• Added a bit better mobile layout for Dashboard, Office Overview, Aircraft Overview, Routes Overview and Open Route main pages.
  
  
• Statistics page currency code format changed from "1000 USD" to "$ 1000" (for better mobile compatibility).
  
  
• Notifications about unread messages now say more clearly the game name.
  
  
• Reordered some links in the main navigation menu for better clarity.
