Bug #9017: Fix Growler notifications for DIMP compose/message screens

Don't store in the session whether to hide the sidebar/menu or attach 
the ajax notification listener. Instead, do this per request and pass 
the request parameter through with Horde::url(). Fixes bug 9017.

I'm not sure how this would help us. We need to keep the ajax 
handler/mode attached as long as the user navigates the traditional 
apps inside the iframe. But as soon as he navigates to the traditional 
app directly, the handler has to be removed.
The only way that comes to mind is to carry a flag around in all urls, 
as soon as we open a traditional page from the ajax iframe.
The same problem applies to the hiding of the menu in the prefs btw.

The only practical way of doing this that I can see is to define, in 
each application's init() function, this pseudocode:

if ($GLOBALS['registry']->initialApp == CURRENT_APP) {
     $_SESSION['horde_notification']['override'] = ($is_ajax_view)
         ? Ajax_Display_Handler
         : null;
}

The better solution would be to abstract all notification code out of 
the framework libraries, create a Utility object that sits between the 
injector and the Notification library, and then have the initializing 
application doing something like:
$injector->getInstance('Horde_Notification')->setMode('ajax')

setMode() would do the necessary push/pop of the Notification handlers.

Once an ajax interface has been loaded, any status notifications no 
longer are displayed with the traditional status handler. This has 
been done so that traditional apps running in an iframe of an ajax app 
returns notifications as ajax responses.
But for the time being we will have both kind of apps side by side, 
i.e. users will switch between them. So we need a way to get the 
traditional status back.
