add a copy button
We should look at adding a copy content button for the HTML / CSS / JS parts so if people need to they can copy / paste the code from the WebUI.
- perhaps it should include a 'there be dragons' notification making sure they're aware of:
- what could change
- that the mark up relies on this / that / the other
Copying a patterns CSS without copying any relevant Elements CSS will make it 'not work' so we need to make sure that the index.SCSS
has all the relevant .SCSS partials
