Description

Reports of a few issues with evolving items:

1. Evolving items can be mailed, but cannot be retrieved. It makes the sound like it's being delivered, but never detaches and goes into the inventory.
2. Evolving items cannot be placed on vendors for purchase. You can list one, but multiples will result in only the last entry being displayed.
3. When sold to a vendor, evolving items cannot be repurchased. The merchant UI crashes out and you must camp and come back or zone to buy or sell anything again.
4. Minor, but linking evolving items results in a number or letter prefixing the item name at all but the final evolution level.
   Please include a summary of the changes and the related issue (Why is this change necessary). Please also include relevant motivation and context. List any dependencies that are required for this change.

This PR resolves 1, 2 and 3 above. Please note, when selling an evolving item to a merchant, any progression is lost. When repurchased, progression is set at 0.

I am not an expert on saylinks, so have not looked into item 4. Anyone with info in this regard please let me know. If I have some time, can look into it further.
