Quick actions in shell component

[rafaelramalho19]

We can add some quick actions to the shell component to further improve the UX.

My suggestiond would be:

• Copy button that copies the content of the entire shell
• Copy line button that copies a specific line
• Anchor line, which would change the URL to refer to that line. Makes it easier to share the lines to other users.
