Make :q in vim mode behave more like in vim when splits are open
Review Request #109006 - Created Feb. 18, 2013 and submitted
The patch changes Kate's behaviour on :q so that it won't close a file, when a split is open, but instead closes the split. In a previous mail to mailing list, I noted that this would cause some crash, but the crash isn't related to my change (see https://bugs.kde.org/show_bug.cgi?id=315391 for information about the mentioned crash).
Compiled and tested by opening several splits and closing them via :q.
