Level Editor Improvements

Over 1000 levels have already been uploaded from the circloO level editor! It's been awesome to see all that creativity. This update adds even more options to the editor, and makes it easier to find your way among all the levels in the level browser.

This update:
- Adds the superglue connection for moveables. This is a very strong connection that is great for making a large complex moveable shape.
- Adds the hinge connection. This is great for creating hinges or wheels.
- Adds a collectable that breaks all connections to the player.
- Makes it easier to create arcs whererever you want them with the new through-three-points creation option.
- Allows you to exactly position most basic shapes by using the new coordinates option
- Adds a search function to the level browser
- Adds a Fresh category to the level browser, with the highest rated levels in the last week
- Makes it possible to see levels you uploaded in the level browser
- And more!

Enjoy!
