Comment 5 for bug 592578

This can be in high value for people in production which need to draw sizes of connectors and such for integrating with a casing. I think this is a other feature than a comment layer (which normaly is only used for text). Also this pops the question from my mind if pcbnew is able to add/remove/move up/move down layers on the layer stack. Then people can make the choice how they organise layers themself and how they give them names.
