title: Configuring globally installed eslint
body: <p>I installed globally eslint@4.2.0 and wanted to use some predefined configs. When I tried to install <code>eslint-config-google</code> it said that I don't have eslint>=4.1.0 (which I had of course, but installed globaly). The same problem occured when installing <code>eslint-config-airbnb-base</code> - ultimately predefined configs can't see globally installed eslint (and even <code>eslint --init</code> can't see it cause it installed another instance of eslint locally when I run it). Then I decided to install both eslint and configuration files locally, in my projects directory - works like a charm, but still I'd like to have these things in global scope so I wouldn't have to care about it each time I make a new directory for my projects.
  Is it possible to make eslint and predifined configs work at global scope or at least have global eslint and local configuration file? </p>
