please add DCMIType vocab

from http://purl.org/dc/dcmitype/

I think I'm gonna have some delays in getting my contributor release docs together (boss is away for a week or more), or I'd do a pull request.

This should be an easy auto vocab generation. Might I suggest DCMIType as the class name?

Thanks!

Should be fairly straightforward. Probably get it out in the next couple of days.

Thank you!
