+ LEVEL EDITOR (FINALLY) (WOOOO)
Accessed through main menu
Left click to draw the tile you have highlighted
Scroll the mouse wheel to select a different material (you'll have to
move to a different tile before it updates, not sure why it's not
redrawing)
Right click to delete a tile
Level is automatically saved to res/level/testCopy.lvl when you draw or
erase a tile
You have to refresh the project and rerun the game to see changes

Note: at the moment, only regular Walls can be drawn in the editor.
I'll add the others after I make a menu with which to swap out

* Changed main menu music (I got annoyed with the old song)
* Loading the playable level will always load testCopy.lvl, test.level
is as of now reserved as a backup of the original, nice-looking level in
case I majorly fuck up testCopy
* Removed some annoying stacktraces from sound.
