Requires node v4 downgrade and rebuild

[blahah]

On initial npm start with node 5.7.0 I got:

App threw an error when running [Error: Module version mismatch. Expected 46, got 47.]

Downgrading to 4.3.0 and running npm rebuild got it running.

I had the same issue with 5.3.0. I can't quite remember how I resolved it but it was some combination of removing global electron-related modules, reinstalling, and rebuilding (both global & local modules).

There was a similar issue here that has a few troubleshooting leads.
