Elf changes

To compensate for the huge protections the elf countries have in all areas of the game, the following changes have been made to the elf specialities today:

- Harmful spells require more runes (+400% instead of the previous +100%)
- Harmful spells cause a +3% strength loss
- The -20% thievery effectiveness on harmful actions has been changed to -80%

Effectiveness of non-harmful thievery actions (such as stealing gold, runes, scrolls) remain unchanged at -20%.

Other specialities of the elf remain unchanged.
