`npm run icon-gen` builds icon files from png files in the images
directory, outputting to build/icon.{ico,icns} (the expected location
for electron-builder).

Set NODE_ENV at run time or build time to switch the app between dev and
production modes.
At build time, the current NODE_ENV will be included in the packaged
app's package.json file. At runtime we read NODE_ENV from package.json,
but also allow the local environment variable to override. A query
string parsed by a preload script exposes the value to the renderer,
which then determines whether we use the staging or production server.
Additionally, different environments have different user data
directories.
// FREEBIE
In package.json, define our main entry point for electron, and add a
node script to start it up.
Add main.js from Electron/electron-quick-start with two modifications.
1. Load background.html instead of index.html
2. Disable node integration in the renderer
At this point we can load the background page in a window
with `npm start`, though it currently breaks on missing chrome app APIs.
// FREEBIE
Set up grunt with tasks for:
* preen - deletes unused files from bower_components, configured in
bower.json
* concat - concatenates preened bower components, configured
automagically from the preen config
It's worth noting that this setup assumes the order of files within a
package doesn't matter. This is usually true since we often include only
one file from the package.
