Sizeable 1.6.9: Sound Settings & Fixes

Hey everyone,

Just a quick update, since I finally got around to adding sound settings to Sizeable! Sorry it has been so long before these settings were added, but Sizeable started out as a project for my masters degree, so it wasn't coded as cleanly as it should have been! Adding these settings took a lot longer than expected.

If I find the time in between other projects of ours, I will try to add a windowed mode to the game too.

I also fixed some stuff in the Diorama mode (deleting not working for example). Hopefully this will make your diorama building expierence a lot better!

Cheers, Sander Ambroos & the Business Goose Team
