Update to Shillelagh to filter for only quarterstaff and club base weapons

[bsleys]

I've tweaked my version of the Shllelagh itemMacro to filter the weapons for only quarterstaff and club weapons. here's the changes I've made replace the current let weapons = ... with the following.

let weapons = tactor.items.filter(function(item) {
  if (item.data.type == 'weapon' && (item.data.data.baseItem == 'quarterstaff' || item.data.data.baseItem == 'club')) return true;
  else return false;
});
