Introduces a simple way to give a proper semantics of `button` to links that behave like UI controls when JavaScript is on and behave like actual links when JavaScript is off. First implementation on the Terms list table. Patch prepared during WordCamp US 2015 Contributor Day. Props mcapybara, garusky, takayukister. See #26504. Fixes #34867. Built from https://develop.svn.wordpress.org/trunk@35947 git-svn-id: http://core.svn.wordpress.org/trunk@35911 1a063a9b-81f0-0310-95a4-ce76da25c4cd
