Restore toggle work from 0.2.0
Rename Toggle to ToggleSwitch for consistency with Montage base class.
Digit ToggleSwitch based on Montage's AbstractToggleSwitch.

- Update a few places where I missed the name change from toggle to toggle-switch.
- Class is now just an empty subclass of the base.
- Use montage namespaced classnames for things now managed by the base class.
- A simple test.
ToggleSwitch styles more cross-browser.

- Add alternate vendor prefixes and non-prefixed rules for transforms, transitions, and gradients.
- Remove unintentional test html file.
