Finalized UI

We now have an updated bell UI. There was a bug has been fixed where more than one type of bell could not be updating at the same time, but that has been fixed. The tether bar is finalized. We also have new pop-ups to help the player through their gaming experience.

New kismet nodes are responsible for fixing the bug. A new Stop UI update node prevents bells from updating when they are no longer activated.

The pause menu has been implemented into level two. We also have new menu options for viewing the controls, and setting the game resolution.
