Remove or make class pattern optional

[tomfa]

Use same pattern as e.g. Sentry.

import Vailable from 'vailable';

// Instead of 
const api = new Vailable({ ... });
api.findResources();

// Do
Vailable.login({ username, password});  // Only require to be run somewhere in the application first
// Alternatively
Valiable.authenticate({ token });

Vailable.isAuthenticated() // true/false
Vailable.findResources();

We can do this by storing auth outside the class instance as a default fallback if class itself does not have auth + making all methods static (can static methods use this?) – By keeping the class we can then also allow user to make multiple instances of a client for different users (low pri, I'm unsure of the usecase, but there probably is one)
