Change the user object structure to allow the registration to more than one account of the same 3rd party OAuth service

[splendido]

This is something in the air since a long time ago...
Basically you'd like an user to access her account on a Meteor app using many different accounts from the same OAuth provider.

Before changing UI packages like accounts-ui, useraccounts, accounts-entry, and other packages like accounts-meld, connect-with, link-accounts, etc.

...we'd need to change the structure of the user object from this:

{
  ...
  services: {
    password: { ... },
    facebook: {
      id: 'asldknijasf,.naflk',
      ...
    },
    google: {
      id: 'asadsasdaflkhgf',
      ...
    },
    ...
  }
}

to something like this:

{
  ...
  services: {
    ...
    facebook: [
      { id: 'asadsasdaflkhgf', ... },
      { id: 'opsdnsdhansah', ... },
      { id: 'qwpodmcsaalm', ... },
    ],
    google: [...],
}

Apparently one of the key method dealing with this is updateOrCreateUserFromExternalService which builds selectors like {"services.facebook.id": service_id} to find the possibly logging in user.
There's also an index about this you can find here

This request showed up recently here, but I remember was already raised in other places I'm not able to find out at the moment, sorry.
