Building system improvements, bugs, no more character pixelation. — Ferromon Together Steam update #918

This update fixes multiple issues, especially regarding link battles, which still need a bit of work. The building system now allows for floating foundations, so building bridges will be much more tolerable I've removed the pixel art filter that was applied to the characters. Originally this stood to help bridge the art gap, but the general consensus has been to find a different approach, and so I will. As always, thank you for all for playing in early access and helping me see this through!
