Bug#479851: qt4-x11: should use external webkit library

[Fathi Boudra <fabo@debian.org>]

Hi,

please discuss with upstream people and inform yourself before making 
assumption. There's no good reason to ship both version or to ship QtWebKIT 
from webkit.org. QtWebKit shipped with Qt is the version to be shipped as 
recommended by TT.

cheers,

Fathi
