Text corrections and accessibility

Path of Adventure got its first update after the Android release!

Main changes:

- Corrected and improved texts - thanks to Anthony Crockett!
- Improved accessibility; screen readers now read stat icons
- Improved error handling
- Fixed some bugs

In the mean time, I'm working on a port for iOS. When that's out of the way too, I've got a million ideas to improve the game already :)

Stay tuned!
