[PATCH]: FIx missing connect() in KEditToolbar

When trying to implement editable toolbars for KStars, I ran into problems.  
The KEditToolbar window would appear and provide the correct behavior, but 
the Ok/Apply/Default buttons didn't do anything[1].

After some poking around, I eventually concluded that the problem is that the 
clicked signals for these buttons aren't actually connected to anything.  The 
slots slotApply(), slotOk() and slotDefault() exist, but are not connected.

KEditToolbar was derived from KDialogBase in KDE-3.5, which provided the 
connect() statements for these buttons.  I'm guessing that when KEditToolbar 
was ported to KDialog, the connects were forgotten.

Anyway, I have attached a small patch that adds the connect statements to 
kedittoolbar.cpp.  I understand that this class will likely see huge changes 
when LiveUI comes, but it's a pretty simple patch, so I thought I'd submit it 
for consideration anyway.

Warning: I am getting an application crash when I close the KEditToolbar 
window, but I'm not able to track it down.  DrKonqi is not giving a useful 
BT, and when I run it through gdb, it doesn't crash.  Here's the DrKonqi BT:

Despite the crash, the modified toolbars are retained when the app gets
