• Ensure config directories exist (fixes error)
• Use ConfigManager for server config too

When running make install I am getting the following error

 File "<string>", line 1, in <module>
  File "/tmp/pip-wr32762h-build/setup.py", line 70, in <module>
    'install': InstallCommand
  File "/opt/conda/lib/python3.4/distutils/core.py", line 148, in setup

make build first to make sure you're on the correct jupyter version (I hope?)
