Hotfix 0.0.5 Live!

Very small fix today to address two problems:

1. Fixed a problem with books not being studyable. We fixed this previously, but if your save file contained bad data you still couldn't study the books. Now we ignore the corrupt data so studying should work.
   
2. Frostbite AP is now 1 and you can use it again, but there is a known issue: sometimes the frozen image doesn't appear. Will investigate that tomorrow.
