I'll try to save the state of the forms in the history.

Approach for saving:
All forms register themselves to DocumentImpl (So that we don't need to 
search the whole document for any forms) When a page is added to the history, 
KHTMLPart::saveState() is called. This asks DocumentImpl for any state 
information which needs to be saved. DocumentImpl calls all objects which 
have registered themselves for their state information. 

Approach for restoring:
KHTMLPart::restoreState() reads the state info of the document and passes it 
along via URLArgs. In KHTMLPart::begin() the info is retrieved again from 
URLArgs and passed to DocumentImpl as the state to which the document should 
restore to. When a form registers itself to DocumentImpl() it will get a 
string back which represents its state at the time the form was saved.
The various HTMLElementImpl::attach() functions should query the form to see 
if they should set their value to something else as the default.
(I guess TextArea needs another place for this?)

Any comments or suggestions?

Cheers,
Waldo
