Fixing *huge* memory leak in konqueror: in KonqView::~KonqView() we were just not deleting the HistoryEntries.

No kidding. Each view can contain *a lot* of HistoryEntries, and each entry contains lots of data: url, locationBarURL, title, buffer, postData, etc.

All that was being leaked when deleting konqviews (i.e. closing a tab).

Thanks pinotree for helping out with valgrind and giving me the valgrind output, you rock!
