Add popoverHtmlUnsafe directive.

[NateRedding]

Popover appears to be missing a directive corresponding to the tooltip-html-unsafe directive.

I have added tests similar to tooltip-html-unsafe, and updated the documentation. I also tried to name my commit similarly to how I see other commits named.

If this build passes, could we please include this? It's sort of ridiculous how many PRs have been submitted for this functionality and how little love this feature has gotten. Please merge this.

[NateRedding]

This accomplishes the same functionality as #2187, but does so following the same pattern as tooltip-html-unsafe.

[kentcdodds]

Yeah, looking at the code I think this is a great (and consistent) implementation. Looks like the build passed. Could someone please merge this?

[NateRedding]

This is also a duplicate of #2276, but this PR includes unit tests and documentation updates.

This approach doesn't allow you to add directives or bindings in the content. Is this preferred over #1848 ?

[NateRedding]

It looks like your approach would be preferable. This implementation was intended to complete the framework with popovers in the same fashion as was done with tooltips. For my (unfortunate) case of getting the HTML content that comes with my data into popovers, I believe #1848 provides an approach that would work as well. So, if that one is going to be merged, we shouldn't need this one.

Now that #1848 is merged, this can now be closed as completed :) .
