Having multiple databases per app

[james-boswell]

I would like to propose to allow multiple databases per app. The official docs state it is advisable to have one database per app but I see no reason why this could not be configurable? Something like config.allowMultipleDatabases and then change db-factory.js as follows:

function DBFactory($q) {
  return function (config) {
    if (!_db || config.allowMultipleDatabases)
      _db = new DB($q, config);
    return _db;
  };
}

Interested in your thoughts on this.
