Warn the user when compiling Objective-C files (.m) that includes Qt
Xcode project templates will by default create source files that
ends with .m (obj-c). If you try to include Qt from such files, you
will get a bunch of compile errors, since the compiler will not
understand C++ concepts, such as namespaces.
To ease mixing native iOS and OS X apps with Qt, we print a warning
to the console, so that the error messages are easier to understand
and fix, by renaming the offending file to .mm.
