Updated TreeCapitator 1.5.2

Bringing back TreeCapitator, now with improved tree cutting action! Also
tweaked the config file so it's not too OP. Don't forget to update the
server version, too. and delete the mod_Treecapitator.cfg file manually!
Just to be sure it gets deleted. Client's should be updated from a fresh
install to avoid config catastrophe!
