review changes

removed unused scripts from animationTests and cleaned up some of the formatting of the widget-slider
Updated animation tests
Removed text property from widget-button. Now text is part of the DOM only.
The move method in widget-sketch no longer rebinds data.
Added more animation tests.
few more tests drawing graph in page. Before I go further we should discuss style and coverage.  Cleaned up id assignment in lineGraphTests (ok, Seann, you were right, it's a useful test.)
Added more animation tests.
Merge branch 'upstream/master'
Changed widget-button constructor so it doesn't change config. Uses a local variable to set the text instead.
