Patch: more fx

Based on feedback, this adds more effects to the game and fixes 1-2 bugs. There are still several bugs you have reported in here, but the feedback is slowly making its way in here

First submission was made visible again so anyone can compare it to the newer version

- rat sfx

-impact sfx for most remaining characters

- impact vfx (blood/sparks)

- reverb added to cave

- slightly better sound attenuation settings

- weapon trails

- slow motion death

- bug fix: you can now escape the pool in the caves

- screen shake no longer triggers on enemy death (it didn’t feel quite right)
