Add 'AdditionalIncludeDirectories' to the 'VCResourceCompilerTool' object in the qmake VCPROJ generator

It would be useful if the resource compiler could also make use of the additional include directories set for a project. One can include files inside a (Visual Studio, not rcc ) resource file, but if you want to have it found based on the INCLUDEPATH's the resource compiler has to get the include paths from qmake into the vcproj file. This was currently not possible since there is no INCLUDEPATH_RESFILE or QMAKE_RESFILE_FLAGS like there is for the C++ compiler.
