Use an array for roles in contributor #39

As it's been pointed out in the EPUB 3 maintenance group, EPUB 3.1 doesn't allow content producers to indicate more than a single role for a contributor.

In EPUB 3.0.x it was possible to indicate as many roles as you wanted:

<dc:contributor id="Olaf">Dr. Olaf Hoffmann</dc:contributor>
<meta refines="#Olaf" property="file-as">Dr. Hoffmann, Olaf</meta>
<meta refines="#Olaf" property="role" scheme="marc:relators">mrk</meta>
<meta refines="#Olaf" property="role" scheme="marc:relators">art</meta>
<meta refines="#Olaf" property="role" scheme="marc:relators">ill</meta>
<meta refines="#Olaf" property="role" scheme="marc:relators">aui</meta>
<meta refines="#Olaf" property="role" scheme="marc:relators">pfr</meta>

The Readium Web Publication Manifest is a direct descendent of the BFF project and was designed with 3.1 round-trippability in mind.

But in the context of Readium-2, we want to maximize compatibility with EPUB 2.0.1 and any 3.x revision, which means that instead of having a single string allowed for the role in a contributor element, we need to move to an array of string.

Also cc @camill-a @danielweck @mahavir155 since we'll need the same support in other implementations.
