Accelerated adding of usage examples

If {{usex}} ever becomes the standard, I could change the script to use it and there wouldn't be any objection to the editor switching to the standard, but right now the template is barely used anywhere. The issue of its usage never ended up in the BP, so it really isn't clear where, if anywhere, that template should be used, and widespread use of a template to replace an existing formatting standard is really something that requires consensus.

{{usex}} is much more common now.
