[PATCH] Implement "readonly" attribute

[Dawit A.]

Hi,

This is my attempt to implement readonly attribute for the two elements 
that support it: TEXTAREA's and INPUT elements of type text and password.  
A patch and a small testcase are attached below.

The patch changes HTMLGenericFormElementImpl::setReadOnly to virtual.  This
way it can be re-implemented as needed. The default function now simply does
nothing.  Also, I hacked the RenderTextArea class to add a widget() function which 
seems to be missing unlike the other RenderXXXX widgets.

I do not know if this is an acceptable implementation.  It does work properly as you
can try for yourself using the included testcase, but that of course means nothing 
since I am not completely familiar with khtml's code.

Regards,
Dawit A.
