Number of prepared spells

Got another request from a user. 

This time they wanted to be able to see just how many spells they have prepared in a spellbook. Kind of hard to keep count while playing and when you have imported all the spells from a class.

I decided to separete the number of prepared spells by cantrips and lvl 1 spells and higer.

Im still testing this, and you can see the number of active spells obove the Spellbook-icon or below the name of the spellbook.
