using local name mapping instead of IDs

[bgruening]

At some point, users need to use IDs to reference a workflow or a workflow invocation ... IDs are not handy and hard to type/remember. Docker is circumventing this trick by generating a nice/funny name for each container. We can not do this in Galaxy as Galaxy is a multi-user system and we do not have that many names available, but we could maybe have such a mapping available locally for every user using gxwf. Here is a port to python from the original Docker Go code: https://github.com/shamrin/namesgenerator/blob/master/namesgenerator.py

We could store a ID-name mapping somewhere locally as soon as we have seen an ID (e.g. started a workflow, got a workflow list ...). Or we can make it more explicit and let the user create such aliases for IDs.
