Reduce Duplication in job_conf.

[jmchilton]

You can use macros in your job_conf to reduce the duplication around defining job destinations - see galaxyproject/galaxy@a5a474f for an example. If you don't care that is totally fine - I have no self-interest - just letting you know the option is available. Thanks for building awesome stuff!

Thanks @jmchilton! Will definitely take a look, all suggestions that help us improve are very welcomed! We have actually some questions of things we want to do, wondering if main galaxy project issues is the place for makings those questions or if there is another better place.
