Update Golem as per HoraK request
This should replace !34 (closed), in order not to fall back to the ugly pink golem. It changes golem offsetY -18 in .png, and adds golem offsetY -7 in .xml. Also, it adds the dyeable red colors to itemcolors.xml for "Metal Red" haircolor in order to fix pipeline. Also, put assassin-mask into proper shape to use headmodel, and remove female version. Fix further stuff with assassin mask.
