Xcode C++14 support

Hi

 

I just get started with JUCE so maybe this doesn't make any sense but I added c++14 language dialect support to the Introducer:

(I understand that you dont want get any suggestions via pull requests on github)

 

https://github.com/doubleday/JUCE/commit/6dce9be4387be93589819a1eea5cb3faac8bd4d0

 

Of course I'm ignoring all x-plattform concerns here...

 

Cheers,

Daniel

This looks like a reasonable change and we will pull it in after some testing. Thank you!

Just saw that vanilla Introjucer can do this now!

It also works pretty good with AppCode now.

So thanks a lot for this :-)
