feat(crash): add electron crash reporter

Summary:
Adds electron's crash reporter. This is currently going to a dumb heroku
app I setup: https://github.com/emorikawa/electron-crash-report-server

It's going there for now since I want to first evaluate if this is useful
before spending the time to build it in N1-Cloud and taking the risk of
getting flooded by crash reports.

The crash reports themselves are very difficult to debug since it requires
compiling tools that can read os-specific memory dumps

Electron seems to be crashing fairly frequently for some unkonwn reason,
and this is really the only diagnostic tool we have to potentially see why
