Remove some manual test apps
Removed - Kinectsurface - Has 3rd party code. - qmlcamera - Ugly mess and kinda pointless. - qmlmultiwindow - Test is not relevant and is buggy. - spectrum - Has 3rd party code. Change-Id: Ic28ffddf9e45f51a5320d4ebd0e2b7b373452cb7 Reviewed-by: Tomi Korpipää <tomi.korpipaa@theqtcompany.com>
