UI Overhaul

UI has been re-done to be based on menus that can be opened or closed. I think this just looks better, but it also helps make the game more mobile-friendly for the future because I would like to make the game runnable on mobile eventually (I will likely just add touch support for the web version).

Added some camera movement such as zooming in/out and panning. Controlled with the scroll wheel/middle mouse button.

Added Anti-aliasing, which makes the game look a lot smoother.

Added some wider customization to the dick & futa dick.

Added a new kind of bulge for when the dick goes past the doll body while inside of it.

Also got the built-in Itch.io fullscreen button working on the web version.

The easter egg was changed to be included by default (uploadable background image, still only available on the Windows version), but there will be more easter eggs to come!!!!!

Code-wise, this was a fairly big update so let me know if there are any bugs!!

Feedback/suggestions are welcome as well!!!!
