Web Lag Issues Fixed!

The web lag issues that have been plaguing the game since the jam it was entered to have finally been fixed!

You can now play the web version without any major freezing in the first few minutes of the game.

There's also a few other smaller changes, the following are the most notable:

1. Changed the file name and icon so that the downloadable version actually displays the game's name and icon (rather than the project name and default Godot icon).
2. Updated the data loading process in anticipation of more content - no real change from a player's perspective right now, but more content being added to the game won't cause anyone's save data to be reset.
3. Fixed a bug that would allow the light level to continue to decrease despite the game being paused.

Note: Changes have not been applied to Diving Bell Mayhem since I think it's important to preserve jam entries, flaws included.
