Balance Machaka

[rtyffg]

Tried to make some changes and additions:
- fever fetish should cost 100 gp/turn now (that should make them not too powerful in case of cbm1.6).
- sorcerer can summon 1 disease ward/turn (not autosummon, they were supposed to be makers of these).
- place poisonous and weakening ward spells - to see if these fit tematically.
- ward's needles changed to stun damage - seems to much fatigue from them.
- spider nest2 - just summons some spiders nearby.
- spider nest - launches aoe5 slime and summons spiders at hit location (just seemed tematically fitting like spider ambush).


An another idea - do "risky" spell fit tematically to machaka? Examples: cheap power of the spheres effect with a nextspell of mr negates feeblemind/disease/death or aoe berserking/strentgh of giants followed by mrnegating disease/poison/kill.
