I am currently developing a plugin which extends issues with additional information from a different model. As this information is project specific, I need to handle issue moves across project boundaries.

This patch extracts the array of updatable attributes during a move to a separate function (which can be extended by a plugin) and adds two hooks to initialize the my data and display it in the view.

The actual moving / updating of the data can be handled with the after_update (for move) and after_create (for copy) hooks on the issue itself.
