Provide support for PhD students as well

[NelsonAPenn]

This template and documentclass is designed for thesis-option masters students. Configurations should be added to support PhD dissertations as well.

I've just done a cursory pass on the dissertation formatting guidelines, and the current configuration seems to meet the basic formatting requirements. I haven't checked the page-specific margins, yet, though.

I'll keep a running list of things I find:

• [x] Title page should have option to say "DISSERTATION"
• [ ] The example pages for Figures and Tables both have prefix text prior to the figure/table number (e.g. Figure 1.........###). It's not otherwise listed in the requirements that I can find, and I think it looks dumb, but it's worth noting, I guess.
