Add/Modify Index Page Header Slides

Just wanted to let you know I'm actually working on things.

It'd be nice if I could get some feedback on it, and some advice on how to actually use the test suite. o.O

Anyways, log into the admin account on the homepage and you'll see some fancy new buttons; they do stuff.

I was originally planning on making the header a markdown block; but that doesn't allow for the kind of formatting control that you'd like to have in the header. 

Oh, we're also using a newer version of the bootstrap javascript (yay) since the old version had a bug in carousel that was crippling me, and in addition, we no longer use the "Orbit" plugin (we use the bootstrap carousel instead) since that had even MORE crippling bugs when you tried to control it with javascript, and besides, we were using bootstrap already anyways, why use another plugin just for the carousel when bootstrap already comes with one? (Note: still need to remove Orbit from the repo.)

So, main feature right now is that the main page header is now editable by admins, loads content from the db, and has fancy live-previewing. We should try to get live-previewing into all of our edit dialogs; they really make it easier to put a page together.
