For BigEndian we don't have to invert the array access if we just iterate backwards :)
Fix xmldoc for gen1 trades ampersand
Add xmldoc for enc trade classes
No functional change.
hovering would grab ILocation, which didn't use the flexible met location fetch.
Just repoint stuff and have it as a virtual call, since most of these are fixed values, there's no point increasing the size of the classes besides those for gen4.
