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

[#1]

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)

We would also like to be able to copy proofs to another object.

We create issues with a proof then send that proof to one set of reviewers to mark-up changes. We then convert that issue to a project and need the proof comments to move along with the document so the production team knows what changes to make.

Currently the document move to the converted project, but the proof does not.
