Title: Removing explicit [global] object references.

For mocha's tests:

```coffeescript
Spine = (global or window).Spine or require('spine')
```

was introduced, but `global` reference throw an error in browser. To avoid this:

```coffeescript
Spine = do -> @Spine ? require 'spine'
```
In fact, lambda `->` makes loose the context so `this` — inside the lambda — is bound to the `global`/`window` object.
