Update v0.3 - Shops added!

• Shops (should) work now!
  • At first, I'd recommend having both this and the original client connected to verify if the shops are really working as expected. I did a test run and everything was synced, but be warned!
• Scrolling through the menus now work as expected using touchscreens!
