Overhaul carousel a bit more:

* Drop custom type arrow controls for glyphicons icons instead for more consistent rendering
* Remove the captions and instead let folks implement what they want in the carousel
* Move the indicators to the bottom middle instead of top right
* Lighten up gradients on the edges for less harsh lighting
All Glyphicons now require a base class, e.g. .glyphicon.glyphicon-star
