🐛 Bug Fix

• install dcmstack straight from github until it is released #593 (@yarikoptic)
• DOC: provide rudimentary How to contribute section in README.rst (@yarikoptic)

⚠️ Pushed to master

• Check out a full clone when testing (@jwodder)
• Convert Travis workflow to GitHub Actions (@jwodder)
• BF(docker): replace old -tipsy with -y -all for conda clean as neurodocker does now (@yarikoptic)
• adjusted script for neurodocker although it does not work (@yarikoptic)

🏠 Internal
