util.xtemplate: Use same argument order in filters even without 'args' This removes the different argument order used between '{x|foo}' and '{x|foo(y)}' because the differing order was awkward and confusing. This util does not seem to be widely used so should not be problematic to change this part. The only known use is in mod_pubsub, which does not use the filter function feature.
