Fishin' and the killin' power of rock also trash is permanent

[AmoryBlaine]

• Updates fishable table to include crabs and squid.
• Removes timer on all instances of garbage in the game. No more magically disappearing trash.
• adds rocks you can find and use to kill things.

Leave garbage items marked as garbage. If you want to change how they get cleaned up, look in the item_cleanup subsystem:

cmss13-pve/code/controllers/subsystem/item_cleanup.dm

Lines 5 to 6 in c8f4e3a

	wait = 10 MINUTES //should be adjusted for WO
	var/start_processing_time = 35 MINUTES //should be adjusted for WO

No need to change any garbage = ... lines at all.

Other than that, code looks good.

[Doubleumc]

Just some dangling changes.

Otherwise looks good.
