New Template System & Main Page Cells

My template system is complete... at least the first version of it.  The cells for each page are now loaded dynamically via database entries, which will allow me to create a nice custom admin system in the future.  I've also added cells to the index page: one for a welcome message, one for login, and another for registration.  The login/registration cells will expand to show html forms.  Once logged in, all three cells will disappear and the layout updated.

Cells added for welcome message, login & registration
