Hi folks,

After another fit of misspelling in a web form today, it occurred to me that 
it would be rather nice to be able to spell check things in HTML forms, 
namely in text edits.  This is potentially useful for webmail, online forums 
(a.k.a. the dot).  Thinking about it, I'm surprised that this hasn't been 
done before...

This patch adds support for doing so to the RMB menu of TextAreaWidget in 
KHTML.  This can improve a bit -- i.e. actually tracking progress in the 
original widget and such, but that can come later.

If nobody objects, I'll commit this in the next day or two.

Cheers,

-Scott
