small issues on example

[paolo-scoppola]

Hi,

I've recompiled the addons on WIN 10 + OF 0.10.0 + Visual Studio 2017 and OSX 10.11 + OF 0.10.1 + Xcode 7.0.1

1. bDetectBeat is not defined in the example, so beat detection randomly not works
2. without calling ofSoundStreamClose() in testApp.exit() the app crash on exit.

Cheers,

Paolo

Sorry I found right now that you call enableBeatDetect in the class constructor. Anyway, at least on Window, the app randomly print 0 on the three beat values. I will check
