Corrected Dublin Core Terms namespace

[Bobulous]

Modified namespace prefix from "dc" to "dct" within the span element for the title, to match the xmlns:dct declaration for the Dublin Core Terms namespace.

Description

Unless I'm misunderstanding the intent of the code, the span element for the title is trying to refer to the Dublin Core Terms "title" property, in which case I believe it should be referring to the "dct" namespace prefix declared within one of its ancestor elements.

I'm going to close this PR, please include these changes in #134

[akmadian]

My apologies, I didn't see your comment about editing multiple files per patch in your other PR :) The changes look good to me, i'll wait on Olga's approval on your other PR to merge this one

[Bobulous]

Yeah, I did try to get both changes into a single pull request, but couldn't find a way to do it. If someone knows the secret, let me know.

@Bobulous , thank you for your PR! To be honest, I am not very familiar with the markup. I used the markup from this document to write the metadata with dc: for title, but a more detailed guide on ccREL does use dct: for title. I am merging the PRs, thank you for your contribution!

Changing dc: to dct: in ccREL markup.
