Remove SetterLink component

[chawes13]

Instead of using this component, we should be pushing devs to use semantic form elements (e.g., checkbox, radio group, or select).

Not only is this not a semantic element, it's also an inappropriate use of an anchor tag, since it's not used for navigation and is not in the tab order. Source: http://itstiredinhere.blogspot.com/2014/08/the-anchor-button-bad-for-accessibility.html.

@bhennes2 @inveterateliterate @dianacamacho Are you aware of any projects currently using this component? I did a search and found it in mmrf and uolf. I recently had a conversation with Nikki about replacing it on uolf, so there may not be any other active projects using it. Let me know if you have any concerns with removing it!

[inveterateliterate]

I have not seen this in the projects I have been active on!

Outside of uolf, i dont think so!

MMRF is idle so should have to worry about backwards compatibility there.
