γ0.20 is out!

Added copying and editing of online levels!
- You can now create copies of online levels (if they are unranked) in order to view them in the editor and give feedback to the creator during the ranking process
- The creator of a level can now create a copy and modify it and then update the online level with the changes made
- Also added a refresh button to level pages so you can update them to the newest version at any time
Unranked levels no longer have leaderboards now that they can be modified
Mods now display under usernames on leaderboards instead of to the right of them
Other Fixes:
- Fixed a bug where local level star calculations would be applied to the wrong level
- Fixed a bug that caused the game to not replace uploaded levels with a bookmark
- Improved menu animations to hopefully fix some performance issue
