Update 1.1.3: Catalog price balance

Hello,

This time a quick update for Shepherd regarding prices in the Catalog:
- Gold sheep price increased from 20g to 25g
- Ram and Alpaca price decreased from 14g to 12g
- Sleepy sheep can now be sold as a part of the common sheep

Wooly sheep changes:
- Wooly sheep price decreased from 14g to 7g
- Wooly sheep wool growth slowed down by 1 day per stage (takes total of 6 days until max growth)
- Fixed visual value and sell prices of Wooly sheep. 
- Wooly sheep will now correctly sell for their current value. 
- Selling Wooly sheeps will be in order of the highest value first. (technically just the first/oldest sheep, which will always be the one with the most value)

With this, the Token count is now at it's limit, so it may be harder to implement further balance changes for the game.
Still, I think it's at a great spot now.

Thank you for playing Shepherd
