Remove C++98 support from the Projucer's Xcode configurations


Due to the #error below (from the juce_TargetPlatform.h file), it seems useless to give the user the option to compile against C++98 with JUCE.

#ifdef __clang__
  #define JUCE_CLANG 1

  #if ((! __has_feature (cxx_nullptr)) || (! __has_feature (cxx_rvalue_references)) || (! __has_feature (cxx_static_assert)))
   #error "Clang 3.2 and earlier are no longer supported!"

In my opinion, it’s misleading to give the option if JUCE isn’t going to support it.


Agreed. I’ve removed these options.
