Generated MSVC project fails with DBUS_ADAPTORS or DBUS_INTERFACES and moc

The qmake MSVC project generator doesn't correctly support DBUS_ADAPTORS or DBUS_INTERFACES under QT += dbus, if the project also contains other moccable files. The project correctly runs qdbusxml2cpp to generate C++ source and header files from the XML input files, but does not run moc on those generated header files.

The fix is surprisingly simple, and a patch is attached. It seems that each VCFilter needs a unique name. By changing the .name of the relevant QMAKE_EXTRA_COMPILERS entry, we ensure that its VCFilter can be correctly stored and retreived in VCProjectSingleConfig::ExtraCompilersFiles.
