2.0.0

• Added options: debug (console.error is surpassed by default) and promprt (to specify string in prompt - default is 'Copy to clipboard: Ctrl+C, Enter'). Contribution by @evenchange4
• Switched back to using textContent to work around issues with trying to copy content that needed escaping, but preserving newline to be able to copy multiline text. Idea by @shvaikalesh
