Review request for Kate and kdelibs.
Changes
-------
Ok, I've worked a bit on style, naming, and making this yet easier to use.
As a demonstration / test case, I'll inline a very short additional diff that fixes \
the described GUI synchronization issues for kate.

Summary
-------
First to sum up the problem, I'm trying to solve. I'll use konqueror as an example:
1) Fire up two instances of konqueror. In one of the instances, set the shortcut of \
"Show History" to "Shift+F6". Now switch to the other instance: The change has not \
been propagated. Ok, perhaps you did not expect that to work in the first place, but \
now: 2) Fire up a single instance of konqueror, the open a new window (File->New \
Window). Do the same game as in 1. The change is not propagated between the two \
toplevel windows of the same konqueror instance, either. Finally: 3) Fire up a single \
instance of konqueror, with a single toplevel window. Open a second tab inside this \
window. Navigate both tabs to e.g. http://www.kde.org. Switch to tab A. Change the \
shortcut of "View Document Source" to "Shift+F6". Take a look at the "View"-menu to \
see the new shortcut. Now switch to tab B. Take another look at the "View"-menu. The \
shortcut is still at the previous setting, here. Switch back to tab A. The shortcut \
is back to the previous setting as well. 4) If you like to, play games 1-3 with \
modifying the toolbars, instead of shortcuts.
So much for the bug description. Konqueror is not really to blame, here, and neither \
is it the only application to be affected. The problem is that we're missing a \
mechanism to synchronize user settings between separate instances of KXMLGUIClients. \
That's what the new class KXmlGuiClientSyncer - contained in this patch - does. See \
the API-documentation within for usage details. For the "essence" of the code, see \
KXmlGuiClientSyncerPrivate::uiRcFileChanged().
Some points, I wasn't sure about:
1) Originally, I tried to incorporate this into KXMLGUIClient, directly (or rather \
KXMLGUIClientPrivate). That would have allowed for *fully* automatic synchronization, \
i.e. without having to register/watch the clients manually. However, kio depends on \
kdeui, and this would have added a cyclic dependency back to kio. Any idea on how to \
work around this? Or this semi-automatic solution safer in the first place? 2) I \
placed this inside kio, pretty much for the reason above. Is this appropriate? 3) \
Which kDebug area to use?
