Implements quest You Call That a Knife?

Steps to test these changes

Setup:

• run dbtool update to get cook mob position update

Pre-Requisites:

• Khazam Reputation 6+

Quest:

• Trade a Sandfish to Mhebi Juhbily (!pos 40 -11 -159 250)
• Trigger the Shed to trigger CS with Mhebi Juhbily -- Quest Start
• Talk to Vah Keshura (!pos 30 -8.5 -105 250)

• Talk to Mhebi Juhbily with Key Item Nonberry's Knife -- Quest Complete

Notes:

• It is not required to kill the mobs spawned by a bad trade to Chef Nonberry, you can trade the correct item at any time to get the Key Item
• The Shed does not seem to have a post quest + zone event
• Spawned Mob positions are estimated from the video capture (It looks like the capture cut out too soon so mob positions were not saved out?)
• Capture showed 10min repop for mobs
• Capture shows new default event for Mehbi Juhbily post quest and zone
• Mobs can only be popped while on quest
