Spider tweaks

Reworks the spider "fur" to something marginally more realistic, links the chitin and fur branches, and adjusts a dream now that spiders sleep in webs.

Fixes #10616.
Incorporates BevapDin's fix and corrects a few debuffs I missed.
Gives Insect the compound-eyes mutation too.
Limit bot weapon usage (no rockets for squirrels)
Priority system for automatic turrets
Move power rating to creature.cpp
Actually move it
Ensure distance to target is respected
Unbreak hostile turrets
Don't let turrets recognize zlaves
Cap focus at 60 if player is Dead Tired
No more dragging cupboards.

Cupboards are part of the floor/wall. If you can drag it around it's a
table.
Reinsert processed items at their previous location instead of appending to the item list.
Remove rotted away items frommap with i_rem().
Remote vehicle controller enhancements
Removes compound eyes from spiders.

Apparently this one was mis-located since Whales-era.  Better late than never.
Let bots not charge at weak stuff
Less unnecessary boo_hoos
Prevent turrets from shooting harmless stuff
Ensure it actually is docile
