Ease of deletion of dashboards

[victorlopezse]

In order to be able to use certain features (e.g. ability to edit a content pack), one needs to create a copy. This is a pain but I can deal with it, what it's really confusing is the deletion part. When a user deletes a dashboard the report is still there. It should be easier to delete a copy you previously created. Also it'd be nice if on the report interface there was a "Delete" button.
