Just use the english locale for now. Load locale data from the
filesystem in the main process and pass it to the renderer preload
script via ipc. Note that we need the locale data to be available by the
time view scripts are loaded.

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.
