More fixes!!

• Fixed spirit limits not being reset when earning XP on a different day than the previously recorded day.
• Level data is now compressed when sent to and from the server.
• Removed the creation of a separate thread for level loading, as my poor implementation blocked the main thread anyway.
• Fixed issues with the scroll bar in the new property editor GUI for arrays.
• The new property editor GUI for numbers now updates the value when the enter key is pressed instead of only when losing focus.
