Initializes the SDK.

The `options` parameter can have the following properties (optional if not
stated otherwise):

* `clientId` (**required**) - The client ID of your application

* `session` - If your application has stored the session object somewhere,
you can pass it to the SDK to speed up the login process.

* `electron` - `true` if **Electron** is used.

* `nw` - `true` if **NW.js v0.13 or higher** is used.
If you use **NW.js v0.12 or lower**, set to the object you get
by calling `require('nw.gui')`
