Propagate "Copy to Clipboard" feature across ECL Watch

There is a "Copy to clipboard" button on the WU Details Summary page (Copy WUID), it would be great if that feature was available throughout ECL Watch.

The WUDetails implementation can be seen:

• https://github.com/hpcc-systems/HPCC-Platform/blob/master/esp/src/eclwatch/templates/WUDetailsWidget.html#L81
• https://github.com/hpcc-systems/HPCC-Platform/blob/master/esp/src/eclwatch/WUDetailsWidget.js#L139

So essentially consists of two pieces, a html button which references the HTML element you want to copy the details from
Importing the clippy class and "attaching" it to the button.
