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 make this possible, the UnitTestRunner class creates a master seed value
for the run, writes this number to the log, and then this method returns a
Random object based on that seed. All tests should only use this method to
create any Random objects that they need.
Note that this method will return an identical object each time it's called
