This commit merge all our work about new UrlBar.

DISCLAIMER: this is far from perfect, but we finally have a good starting point to work on.. :)

Jonas Gastal started working on it in the 0.3 times, startin from CompletionBase code ..
.. I did some work on another idea, proposing (in code) a new "suggest engine" created from scratch...
Lionel Chauvin finally merged our ideas and implemented what you are seeing (and improved it, too!)..

- New suggestion items (Firefox style)
- a mockup on the known urls (rekonq style)
- for now, automatic Google and Wikipedia searches (more coming)..
- a beautiful animation :)
- quite all rough edges smoothed
