require() in .hyper.js config

Hi! I'd like to use require() in my .hyper.js, but I get a ReferenceError when doing so. Could this be added?

My specific use case is the following:

let fs = require('fs');
module.exports = {
    // ...
    shell: (() => {
      let userPath = 'C:\\Users\\niklas\\Applications\\Git\\bin\\bash.exe';
      let systemPath = 'C:\\Program Files\\Git\\bin\\bash.exe';
      if (fs.existsSync(userPath)) return userPath;
      return systemPath;
    })()
};

Eventually, I would like to set some configuration values based on the current platform, too.

The issue names only the .hyper.js configuration file; start by locating where Hyper loads and evaluates that file. Confirm how require() could be made available and how platform-dependent values should behave, then verify the supplied fs.existsSync example and related configuration cases.
