Autoupdating

[adamtowerz]

Electron supports autoupdating (https://github.com/electron/electron/blob/master/docs/api/auto-updater.md). This is a necessary part of release 1, as it allows users to easily transition to future releases as the app develops.

So to use the autoupdating features we need to codesign our app (on mac atleast) which is nice 99$ fee per year, so for now i guess we proceed for card1.0.0 without autoupdating?
