Otherwise everyone that builds electron vector will end up with
their apps auto-updatin to our version when we release an update.
Coming next: A way to manage our electron release process to make
sure we never ship a build with auto-update disabled.
* Implement the squirrel install / uninstall hooks (so we have
a start menu entry / desktop shortcut)
* Wait longer before checking for update
* Set the window icon
* Add a 'file' menu
* Bump electron-builder
* Add the icon url for the control panel entry
