Custom Ball Merge Update 0.4.0

This update includes the following new functionality:

• Game screen UI element repositioning (score box, next box, today's best box, evolution graphic and each item in the evolution spiral)
• Evolution spiral item size customization
• Custom background images can be added to the score, next and today's best boxes, completely changing the appearance.
• The game over screen elements can also be customized in color and graphic assets, including the button textures.

Most of the new functionality comes from additional parameters in the advanced.ini file. Unfortunately, I have not implemented a visual editor for it, so you'll have to edit the parameters in the text file manually and load the skin in the game to check the results, repeating this cycle until everything looks the way you want.

Additionally, there are some small bugfixes.
