Globally install powerline

Today I’ve tried to globally install Powerline. That was a bit of a pain because it has no global config files.

Quick and dirty how-to:

1. Add XDG_CONFIG_DIRS=/etc/xdg to /etc/environment if it isn’t already set,
2. Copy the config to /etc/xdg/powerline,
3. Customize config,
4. Load powerline from /etc/bash.bashrc, ~/.zshrc, etc.

My config can be found at on Github
