Update shortcode-register.php

Hi,

as I stated yesterday in a comment on your blog entry http://164a.com/franklin-roadmap/ , i'm very happy to see that appthemer-crowdfunding is not completely dead.

I'm not sure if this repo is open for pull-requests, i'll post this anyway.
Its a quick fix I pull-requested for the astoundify repo and which got accepted just some hours before they deleted their repo.

hope to hear from you,
Mirko
