Force anonymous

[richardolsson]

Add an option (per request) to force anonymous requests, i.e. to not sign them using any available token. Could be something like:

// Options to resource()
Z.resource('users', { forceAnonymous: true })
    .post(myData);

// Or, method similar to meta()
Z.resource('users')
    .forceAnonymous()
    .post(myData);
