wordwrapping problem outdated?

[Eugeniu Plamadeala]

This is a patch that gets rid of some outdated code.
The reason it was there is:
" // Enforce <p>text</p> otherwise the word-wrap doesn't work well"

A certain qrichtextify(QString&) function was used to do that. Well, I've done 
some testing and it appears that with Qt4 wordwrapping works nicely for 
labels, so I see no reason to keep the old function.

It was used only in kmessagebox.cpp and kpassworddialog.cpp
Please take a look.
