Minor bug fixes.
Fix for rare crash on hard rain.

Witches now will always sit down.
Added a 1 in 10 chance per survivor every 10 second spawn cycle to spawn a witch directly behind said survivor.
Massively streamlined code.
Witch speed reduced 15%
MORE WITCHES THAN BEFORE.

I balance it to make sure you(by you I mean I) can actually beat this on most maps before I release. You just need to get good.

Fixed an isssue regarding witch spawning. (only one was spawning at a time instead of 10)

Decreased witch health, slight speed increase. Witches have a negative anger rate(Once they spot you, they will always attack.)
