Beta 1.28

Necromancy? Skills? Finally getting more balanced?

- Added more skills that are able to be learned if a character reads a certain book.

- Balanced the Focus gain a little bit for using some spells, still probably pretty unbalanced.

- Reworded and reworked all skills to explain their damage better and cut out some useless information that was previously being provided.

- Tweaked some Mana and Focus cost numbers

- Reduced some damage skills to be more reasonable.
