Yet Another Price Reduction (YAPR), fix mod book for Book of Stars, release location

[Witchybun]

Does the following:

• Reduces prices (again) for Bear and Junimo shops. There was complaints again and at this point I won't touch this again if asked. Happens too much idk.
• Found the method for books, and this should fix the Book of Stars giving EXP to modded skills.
• A lot of players say they cannot find Digging With Worms, and I have had no luck either. Suffice to say its likely its a book that exists, and works, but was not added to the game. If its not added, due to me wanting to match what modders put out in terms of structure, I am just removing this location and releasing this location for everyone.

Finally returned to this.

I've also modified the rates a bit more for barter shops in general, and for junimo/bear. I increased the rates for bear again, but with the sqrt method it seems less evil.
