Small breaking change to JUCEApplicationBase

I found that JUCEApplicationBase::getApplicationName and JUCEApplicationBase::getApplicationVersion return a const String: is it possible to change it to return simply String ? It makes no sense to return a const version if it is not returning a reference too, and it will make my life easier with the juce bindings.

I’m aware this is a breaking change for a lot of projects, but it’s an easy one to fix.
