Copy folders and transfer modules with all nested items

Copying a folder or module in the Solution Navigator should copy its complete contents in one operation, including nested folders, modules, classes, interfaces and enumerations. Developers should be able to reuse a related group of source items in another project or an open solution without transferring each item separately.

Moving a module should also move its nested source items with it. Transfers should preserve the hierarchy, source code, notes, designer information and applicable application/test scope, report conflicts clearly, and be undoable as one operation.

Ordinary Copy/Paste should include the complete selected hierarchy by default. No separate "Paste with nested items" command should be necessary.
