Add ability for child test cases to all be viewed when selecting parent folder.

Currently you can only see test cases when selecting the folder they are created under, when using folders for organizational structure it means having to drill down several times before seeing any content and makes large scale moving/editing/cloning/sharing take large amounts of time.

There should be an option to have all child test cases (that exist anywhere under that parent) be visible when selecting a parent folder. This should also include even the release folder showing ALL test cases in the release.

Create a small visual below regarding Test Case repo but it should apply to all areas with folder structures.  This should probably be a toggleable setting if people use multi-level case structures within parents and don't want all cases in sub-folders brought up.
