Closes #5870

What's Changed

Consolidates the List View Actions into a single button. Displays "Add" split button dropdown as primary unless the button does not exist or the user does not have permissions, otherwise it falls back to "Actions" button dropdown. Uses pull-right to avoid overflowing offpage.

We should probably add a small section header for the "Export" section, when there are multiple export options, so it is clear what those options are for.

I was thinking the same, just wasn't sure how I would do it. Probably just a <li> Export Templates </li> that isn't clickable.
