Done: (e52909d90274) The header arg is :eval no

E.g. by org-babel-execute-buffer

Hmm, should this be a new header argument, maybe :run which can take a yes or no argument?

Perhaps, if it's the case that it won't be used often, we should use :execute so that the terminology is kept consistent with the corresponding function (like "tangle").
