Pet level per zone.

Since the pet battles are working on Frostwolf I figured I should put a small list of pet zones per level since I'm sure someone will be catching pets.
ps. I haven't checked all of these but I'm sure someone wants to catch these small bastards, I will be correcting these in case of some being incorrect. :)
pps. All of the locations that have a Battle Pet Trainer have been linked, I will try to make the maps show where all pets are usually stationed but that will take couple of days.
