Title: Fixed tiles that should be | but were ,

The vertical picket fence, vertical chain link fence, vertical railing, barn door rope and pulley, and palisade rope and pulley all had their tiles changed from "|" to ", ".

Given the space after the comma and the recent jsonization changes, I'm pretty sure this was accidental and caused by using the "change all" function to save time.
