1. Final boss node sprites and titles can be modified.
2. Editor now ensures that each card has a card type.
3. +100% Booshu.

SetSprite(string sprite, int pixelDensity)
- Alternate SetSprite method that takes in a file name.
- Also allows you to change the pixel density of the picture, so you can fiddle with the scaling through code :)

Create<T>
- Added a Create<T> method to allow modders to instantiate their own derived classes of BattleData and still use the BattleDataEditor library.

AddGobblers
- Added a AddGobblers method that allows modders to add gobblers (or a different card) to their fight if the player has the gobbler bell active.
