Dolphin Places: React to Nepomuk system changes

Reload the places panel when Nepomuk starts up and shutsdown. This way
the user does not need to restart Dolphin to see the custom searches and
places after Nepomuk switches on.

fix building tests under windows
Update the required kdelibs version

Since commit b8c9aa55ff06b8bd540f1fa7941e0eb4a3572040, kde-baseapps
calls KFileItem::isFinalIconKnown(), which has been added to KFileItem
in KDE 4.10.2. Update the required version accordingly in the
CMakeLists.txt, such that people with an older version get a CMake
error, rather than a build failure.
Restore the old behavior where the icon is removed from the status bar
when starting loading a new page.

Fix unit test failure

The recent commit 022b564831e2295ee3bb6e53ece53191b40d894a, which added
a few source files to kitemlistcontrollertest, caused a crash in that
test - an assert was hit because now a different virtual method was
called in one place (KStandardItemListView::initializeItemListWidget()),
and qobject_cast could not cast the 'item', which is of type
KFileItemListWidget, to its base class KStandardItemListWidget. Adding
the source file kfileitemlistwidget.cpp fixes this.

Updated the midnightcommander profile to use dolphinpart instead of konq_detailedlistview.

Bug reporter says it still does not fix the crash, but for me it at least restores a working
midnight commander profile.
