feat: track famo.us 0.3.0

BREAKING CHANGE:

Famo.us 0.3.0 introduces some breaking changes.

* Boilerplate:
  * Must change src of famous-global from:
    "bower_components/famous/famous-global.js"
      to
    "bower_components/famous/dist/famous-global.js"

  * May need to perform a `bower cache clean` before updating your bower packages.  Verify that "bower_components/famous/CHANGELOG.md" mentions 0.3.0 to ensure that the update was successful.

* Application code:
  * Famo.us 0.3.0 defaults `align` to [0,0] instead of defaulting to any provided value of `origin`.  In cases where `origin` is defined but `align` is not, element alignment will be broken.  Simplest fix for existing code is to add an `fa-align` attribute that matches `fa-origin` on any element where `fa-origin` is defined and `fa-align` is not.
  * Vanilla Famo.us Surfaces' `eventHandler` member has been renamed to `_eventOutput`.
  * See the [Famo.us CHANGELOG](https://github.com/Famous/famous/blob/v0.3.0/CHANGELOG.md) for more details.
