Don't reset the window type on window show

We were resetting the window type on show, this was breaking some
deployments, since it used to be possible to set the xcb properties from
the user application.
This change requires the user to at least start using the
QtPlatformHeaders before overriding the window properties with the values
set there.

turn off multi-pass RCC for Visual Studio projects

For multi-pass RCC qmake generates broken VS project files, because
the RCC extra compiler directly calls the C++ compiler on a generated
source file. Adding this call to a VS project file will bypass any
project settings. Also, the VS project generator is not prepared to
add extra compilers that generate object files.
