Add ability to clone release

[johnc_1]

We have about 2500 tests at this time.  As the process of connecting that many tests, even organized into test sets, is cumbersome (creating another suggestion for that issue), it would extremely helpful to be able to clone a release or iteration to another release or iteration, and carry across the linked items (we only use tests, not sprints or requirements).  That way, even though I would have to manually link all the tests to a release, at least for the next release, I could clone and be done, and just add any new tests (or test sets).

It's a good improvement for the future. +1
