Add a 'Copy' button to codeblocks

I was going to leave this suggestion as well. Are we just missing it? If not, this should really be of the highest priority. But really, you have the foundation of a really great, simple application. Thank you for all your work :-)

This could be done using customHTMLRenderer by appending a custom button to the content of codeblock nodes with the onclick function that copies the content of the codeblock.

Unfortunately I don't know enough about styling and how Vue does it to implement this feature.

Looking forward to this as well. Copy to clipboard is essential for code blocks :)
