Show prepared only spells

[tsiemens]

User suggestion:

On the Skills page, you have a "Show trained only" checkbox. It would be killer if the Spells page had a "Show prepared only" checkbox just like this. As it is, I need to scroll through my entire spell list to see what I've got prepared. It'd be great if there was a way to record my character's spells per day and save DCs, as well, but the prepared-only checkbox would be especially nice.

Hey! I'm a First time github commenter, I recently started using the app and plan to use it in future to manage all of my games however the above issue is a big omission from an excellent app.

It would be particularly important to be able to collapse the list or show prepared only as wizards do have a tendency to collect spells. Showing spell's per day and spell Save DCs is very important for casters, more important even than most of the combat stats...

This project is not really being actively worked on. Feel free to implement this change off of the master branch for now.
