Add item field: Manufacturer

[maplethorpej]

Add a string input field to an item entity that allows the user to specify a manufacturer or vendor.

You can put this one to bed. Thanks!

This needs to be closed. Nice work!

Just went through and extracted my manufacturers into the new field, and noticed that while they show up in Inventory and while editing a pack, the manufacturer doesn't show up in the pack view mode.
