Investigate ability to remove replace: true in components

[icfantv]

Bootstrap 3's CSS class structure is too tightly coupled to the DOM for our current system of using replace: true in certain directives.

We need to research whether or not we can move the uib-* directives from an E to an A on require and use our templates as normal or with slight tweaks.

We need to consider whether to only support 1.5 for this as well which will allow us to use named transclusions and remove the transclusion hacks we have in place.
