Major update - spells & enemies

*Major update*

It has been a bit quiet for a few days, but finally there is a significant update:

- renamed to: The first hamurai

- 3 fully implemented spell groups: fire, ice & lightning

-- 3 hybrid spells for all combinations of groups

-- 3 ultimate spells

-- total 10+ new spells (incl. 4 passive abilities)

- complete spell description, incl. changes for upgrades

- all spells have icons

- visual indication for slowed & frozen enemies

-- trying out the new style to see if I like it, might change it later

- all spells have damage types now

- 4 new enemy types

- many bug fixes

- many new bugs introduced (I hope fewer than fixed)

I think the game is pretty playable at this point. I'd be happy to get any kind of feedback :)
