Release v1.7.1

blur() results in a loss/reset of keyboard focus, meaning keyboard users usually get thrown right back to the start of the page. Instead, this moves focus back to the trigger (which had the focus when the trigger was activated).
As with the proposed fix in https://github.com/zenorocha/clipboard.js/pull/418 this obviously results in the focus styles (like the default outline, unless suppressed) being applied to the trigger (see the related PR for rationale and future fix using `:focus-ring`)

 The good news is that clipboard.js gracefully degrades if you need to support older browsers. All you have to do is show a tooltip saying `Copied!` when `success` event is called and `Press Ctrl+C to copy` when `error` event is called because the text is already selected.
 
+You can also check if clipboard.js is supported or not by running `Clipboard.isSupported()`, that way you can hide copy/cut buttons from the UI.
