Compile error in connectivity/bluetooth

bluetooth.pri uses the following hack:

INCLUDEPATH += $${QMAKE_INCDIR_QT}/QtNetwork

This assumption doesn't always hold (e.b. MXCL builds of Qt on Mac OS X). I suggest to remove that line from the *.pri and use the standard Qt include path policy:

#include <QtNetwork/QAbstractSocket>

instead of

#include <QAbstractSocket>

That should work on all systems without qmake magic.
