Harvard: include certificate at beginning of dissertation.

[gregreen]

If the option [ddraft] is not supplied to the Dissertate class, it will look for certificate.pdf in the base directory and insert it before the title page.

Harvard requires the "Dissertation Acceptance Certificate" to be included before the title page, but simply merging it in after-the-fact (with pdftk, for example) can mess up the page indexing in the electronic version of the PDF. The print version will still be fine, but in the PDF index, the abstract will be addressed by 3 instead of iii. Using pdfpages to insert the certificate during compilation fixes this problem.

I'm actually going to modify this a bit to include a blank page after the DAC, as Harvard requires.
