Comment 2 for bug 1252301

two bugs here per se.. one is deployments should only be considered in isolation, if there is violation of that isolation it should be a pre/validation check. so only the set of units that are part of the deployment to be considered.

second bug is unrelated, but report/reminder per irc, that the gui wants to continue on in the face of unit errors and that should be an option for embedded gui server use.
