Start container not in background when not a server

[RitchieFlick]

Shouldn't the option -d be optional? Or rather only if it is a webserver? Maybe an additional check on initialization which asks if the container is a simple console application?
Currenlty if one is working on a console application, he/she will simply not see any output from it.
