* Fix stalker/blood siphon unlock
Stalker now unlocks blood siphon instead of rusty. Both rusty and blood siphon are now unlocked by exactly two other knowledges, just like every other side path in the research tree.
* Flame birth description fix
Flame birth's research's description now describes flame birth and not what I assume to be touch of madness.
* Curse of corrosion description fix
Curse of corrosion's description no longer states the ritual requires a pair of hands.
* Further corrosion description edit
I missed that there was one more mistake in the curse of corrosion description, so I changed that as well.
