[sugar] (another) WebKit port of Browse

[Walter Bender]

"Sugarizing" involves more than just the look and feel of the UI; in
addition to Bitfrost considerations--raised by Bert and Mikus--and the
collaboration model, there is also Journal/Datastore intergration to
consider: the trivial from of Sugarizing does not result in useful
Journal entries. So some downstream intervention will be needed in any
case.
