[PATCH] Allow application to use a website for documentation.

[Tom Albers]

Hi, 

As I see a trend that wiki's become more popular. An application developer might decide that he wants the documentation of his application in a wiki instead of a docbook. it might be a good idea to provide some support for that possibility in kdelibs. 

Attached is a - straightforward - patch that makes it possible to call setDocumentationAddress( website ) on the KAboutData object. If the help function in the menu is used, not the KHelpCenter will launch, but the default browser with that website.

I ask permission to commit in trunk and branch, please review, I'm not used to work in kdelibs.

Best,

Toma
