The regular windows shortcuts (eg. minimise, hide) don't work unless
they have menu entries, so add them along with the standard set of
expected menu items for mac (although I've omitted 'about' since it
opens a window so is a slightly more visible change).

Also Electron has a role for 'quit' so use this instead of providing
our own.

With the menu bar gone, shortcuts to reload the window or open the DevTools
need to be done manually. Thankfully electron-debug takes care of this!

Helps with testing, since the webpack dev server uses a self-signed
certificate.

A smaller window makes it for a bad experience.
