0.15.2 - more fixes and Android version!

Version 0.15.2

Another minor update, but this one comes with an android version of the 0.15 demo! I've done what I can to make it look and play nice on a mobile screen, but there's probably some improvements I can make. I welcome feedback on this front, because I don't really play games on my own phone so I don't know what the best practices are! Once again, please be aware that saves are not compatible from 0.14.5 or lower, and that content only covers the first two gathering locations and the Allure and Elasticity potions.

• Tweaked stamina potions and stamina usage. Everything is now in increments of 10 so there shouldn't be any weirdness when you've only got 5 stamina left
• Tweaked the exp curve due to how fast you can grind exp now. Early levels should still come fairly quick but it ramps up after that
• Fixed some buttons showing the wrong thing
