Adjusts trees and vendor spawners

Added some weights to the vendor spawners, basically so the hotfoods vendor will appear less often than any other, and some of the more powerful/special vendors appear less often than the normal ones.

Also adjusts the bigtrees. They were originally made just for gateway decoration, but with GB featuring them, they needed to be brought into line with normal stuff. They still have more health than normal trees, but it's less. Also they have stump sprites now.
