Converting dojo/cookie DOH test to Intern
Convert dojo/_base/connect to intern.
Convert fx to Intern

- dojo/fx
- dojo/fx/Toggler
- dojo/fx/easing
- dojo/NodeList-fx
Update Intern to 2.0.1
Converted tests/Stateful from doh to intern
Converted window and scrollTo tests to Intern

- dojo/window
- viewport dimension
- scrollTo

This is not a one to one conversion. The original scrollTo tests were
hard to convert to intern. These tests run through all of the document
layout scenarios and verify that the target element is scrolled into the
viewport.

The target element is considered in view if the top or bottom and the
right side of the target are within the viewport.
Use an external dojo 1.10.0 for writing tests

- Add dojo-1.10.0 dependency to package.json
- Update test config to map "dojo-testing" to the dojo-under-test
- Update all tests to use the right dojo for the right thing
Don't use intern/dojo for writing tests -- use an external dojo.
