Revert "Solve the problem of the QList<int> hack"

My earlier attempt at fixing worked locally because I had not cleaned up my build dir. If I had, I'd have noticed that it doesn't actually run qdbusxml2cpp.

Now fix the macro name that Ade misspelt.

Also, I urge everyone to upgrade to CMake 2.6, which has a working file-property mechanism, which we would have been able to use here. In CMake 2.4, GET_SOURCE_FILE_PROPERTY / SET_SOURCE_FILES_PROPERTIES doesn't work, so we can't tell the macro to pass the -i flag to qdbusxml2cpp.
