Update to demo 1.1

Changelog:

• Fixed mirror in the forest having minimal reflections.
• Fixed backpack upgrade not actually expanding the backpack array.
• Fixed a few recipes not being enabled by default.  Now you can actually make the seed extractor that makes crop breeding viable.
• Made it so non-stacking items don't show a stack size.
• Fixed the miner mirror being on the wrong starting conversation.
• Fixed some item pricing.  Seeds are cheaper, you can buy all of them if you want, and wheat is more lucrative to farm.
