Oh no! More changes!

Ok, so after making the single master page, I created a nested master
page  for creating all admin pages. Login and registration are working
on my end (but only with my web config stuff). I'll be working on the
database shortly. Assuming everyone is cool with it, here's how I
envision new pages being created:
Feature pages (like index) - based on homePage master
Content pages - based on singlePage master
Admin pages - based on adminPage master

Give me some feedback after you look it over.
