Bs3 mashup

Howdy,

I just thought I'd share some effort I've put into the BS3 conversion - unfortunately I've not had as much time to work on it as I'd like.

There were no big conflicts on the merge except for the index page, which I had modified quite a bit to get the grids working. I did my best to keep both of our changes, but I'm happy to fix things if I clobbered any of your stuff.

I'm just sort of fixing things as I notice them, but the synopsis of differences like so:

**Grunt**
- added additional watcher tasks to aid with development & docs fixing

**Head**
- kept glyphicons from your branch, but also left commented out link for font-awesome. my thinking on this was since they are close to 1:1 with bootstrap/glyphicons, and we wouldn't have to host the fonts.

**Header**
- switched to non-responsive header, as we only have three menu items and collapse isn't working atm
- .navbar-brand dropdown fixed
- added class for navbar spacing div so it can be styled responsively

**Body**
- switched up grid classes to bs3 flavor
- added some styling for tabs
