Unused xml node

[dalvorsn]

I was changing some things in my private repository, based on tfs 1.0, and I saw that the strategy node is not used, it was configured in a lot of monsters like this
https://github.com/otland/forgottenserver/blob/master/data/monster/Canines/hot%20dog.xml
I did not find any line that read it, and anything that use it, so I think so that is a little mistake
