Ability to copy subaction

Copying actions makes it easy to streamline workflow and ensures consistency. Now, users will be able to copy over subactions as well as actions!

To copy a subaction, click on the "Copy" button in the bottom right next to the "Delete" button. When the subaction is copied, the copied subaction will also be added to the parent action card.

The ability to copy subactions will exist for any level of subaction (the subaction of a subaction of a subaction...you get it.)

Thank you to Effectv, J.S. Held, Quantificare, and Marriott for requesting this feature.
