Fix org-export-creator-string' and add the option org-e-html-creator-string'.

* org-e-html.el (org-e-html-creator-string): New option.
(org-e-html-options-alist): Use it.

* org-export.el (org-export-creator-string): Don't use HTML
tags in the generic creator string.

Thanks to Nicolas for directions on what to change wrt this.
