Add Ability to Copy A Proof (and logged Comments) to a new Task

It would be helpful to have the ability to create a Copy of a Proof (and its associated Comments) and attach that Proof Copy to a different Task.

Here is an example of where this would be helpful:

1) Proof is created in "Client Review" Task
2) Client opens that Proof, makes Comments, and a Decision
3) Account Team reviews the Client comments and then COPIES that Client Proof (and comments) from the "Client Review" Task to "Creative Revisions" Task. - we don't want to Move the Proof to the "Creative Revisions" Task, because the client may want to update/reference it.
4) Creative Team can view the comments that the Client made, update and then make a new Version of that Client Proof in their "Creative Revisions" Task.
5) Account Team opens the "Creative Revisions" Task and compares the Client-commented Proof (v.1) with the Creative Team's updates (v.2)
