Patch to fix the bug

It seems that executing javascript code using evaluateJavaScript that changes
the visibility of some divs in a page does not cause an immediate relayout of
the page. The page instead remains unchanged until the user moves the mouse
over it. The problem was found by using js like this:

function toggleVisibility(id)
{
    el = document.getElementById(id);
    if (el.style.display == 'none')
    {
        el.style.display = '';
        window.silk.GM_log('showing');
    } else {
        el.style.display = 'none';
        window.silk.GM_log('hiding');
    }
}

toggleVisibility('sidebar');
toggleVisibility('header');
toggleVisibility('footer');

Executed against a gitorious repository. The same code executed in the
inspector functions as expected. I've included what I think should be a patch
to fix this issue in master, though since my code has kde dependencies against
4.5 I have been unable to test it so far.
