Update doc/usage.rst

I'm new to http methods other than GET and POST and spent a good few minutes searching google for "PUT DELETE"... So I thought I'd separate them somehow in the docs.

Isn't the last item of a list usually separated with "or" or "and"?

Usually yes, not a big deal, but you never know, it might avoid people doing a google search for the "PUT or DELETE" HTTP method ;)
