v0.9.0

• BREAKING: Yank the current animations API
  • This is undergoing a redesign to more effective coordinate animations with each other
• BREAKING: Remove ActionObservable extension to Kefir in favor of #thru & ofType helper function
  • This eliminates the problem of not always having ofType available on the prototype chain of the returned actions$.
• BREAKING: Remove default export from brookjs
  • There's no reason to use this. I borrowed the idea from Kefir, but didn't really think critically about why it should or should not be available here. I don't expect this to impact anyone, as it doesn't affect normal import { ... } from 'brookjs' nor const { ... } = require('brookjs') usages.
