[Camino] [SOC] Improvements to the Camino tabbed-browsing experience

[Desmond Elliott]

Thanks to everybody who contributed in this thread and to everybody who has
wished me luck. We shall be discussing these ideas over the next few days
and hope to have a more definite scope for this project by the weekend.

I shall post back to the list with a link to our final decisions and some
high-level explanations of what we do plan to implement. (maybe even some
diagrams too!)
