fix macOS build (following Projucer changes made in Windows, which removed /Applications/JUCE/modules from its headers). move JUCE headers under source control, so that Windows and macOS can both build against same version of JUCE. remove AUv3 target (I think it's an iOS thing, so it will never work with this macOS fluidsynth dylib).

to the other playSound methods. For example, if you would like to

stop the sound prematurely you can call this method with a

TransportAudioSource and then call audioSource->stop. Note that,

you must call audioSource->start to start the playback, if your

source once the audio source has stopped playing for any reason,

for example when the sound has finished playing or when you have

called audioSource->stop. Therefore, calling audioSource->start() on

a finished audioSource will not restart the sound again. If this is

desired simply call playSound with the same audioSource again.
