[rekonq] New search bar and tabs

[Emmanuel Surleau]

Hi guys,

I just built rekonq's latest git, and my, the new search bar is GORGEOUS. 
Rekonq is seriously rocking by now. While playing with it, I reflected, though, 
that a probably-easy-to-implement feature could be nice: Firefox has this neat 
"undo close tab" feature, which reopens the last tab closed. Now, I'm aware 
that we have a "closed tabs" area in the home page, but it's not as quick of 
use.

*goes back to play with the awesome new search bar*

Cheers,

Emm
