Use LTK Refactoring when copying (duplicating) a Project.

[N1k145]

The Idea is that currently it is not possible to modify a project when it is copied and renamed. This leads to usability issues for example in PDE, where the rename of a project modifies the MANIFEST.MF but a copy does not. This solves this by providing a copy project refactoring that can be extended using a copy participant.

This is related to #2155
This is not done jet, but it would be great if somebody could have a smal look from architecture/concept perspective.
Where I am currently unsure is the using of the CopyParticipants. I have seen there is a MoveRename Refactoring, which is basically a mixture of moving and renaming but that is using RenameParticipants.
Can somebody comment what they think is the correct approach?
