Update submodules and disable some failing repositories

Until dev is fixed, we disable some of the broken repos in the qt5
wip/cmake branch: qttools, qtremoteobjects, qtscxml, qtwebsockets,
qtwinextras.

Also switch Windows to be built in Release mode, to circumvent some
issues with Debug builds that are also present in dev. Note qmake
builds in Coin also only build Release builds of Windows for testing.
