Patch by Benjamin Poulain <bpoulain@apple.com> on 2013-08-27
Reviewed by Ryosuke Niwa.

Clean up of SpaceSplitString following the cleaning of the DOMTokenList hierarchy.
This brings the following:
- Fix the coding style of the header.
- Remove the concepts of empty and null. The list can now be empty or have something.
  There is no null state.
- Put the tokens directly following SpaceSplitStringData instead of using a Vector in between.
