MMDAI2 play does not play .wav file while mortion is playing

[zzrock123]

I have found a few issue and has been amended a some files.
This might raise for Video generator and need to review the change.

- MMDAI/VPVM/ScenePlayer.cc 2013-01-03 22:54:45.000000000 +0900

* Enabled audio in ScenePlay

* Binary released version did not play audio

- MMDAI/VPVM/common/SceneLoader.cc 2013-01-03 22:54:45.000000000 +0900

* Set the saveProject temporary file path -- maybe some other way to fix this

* No issue with binary released version, but an issue in my build

- MMDAI/VPVM/video/AVCommon.cc 2013-01-03 22:54:46.000000000 +0900

* Added detail warning messages

- MMDAI/VPVM/video/AudioDecoder.cc 2013-01-03 22:54:46.000000000 +0900

* Moved m_audioContext and m_formatContext to class member variable

* Removed filter for audioContext->channels == 2 and sample_rate == 44100

* Used audioContext->sample_rate for play back

* Added checks for formatContext.isNull() and audioCOntext.isNull()

- MMDAI/VPVM/video/AudioDecoder.h 2013-01-03 22:54:46.000000000 +0900

* Moved m_audioContext and m_formatContext to class member variable

- MMDAI/VPVM/video/AudioPlayer.cc 2013-01-03 22:54:46.000000000 +0900

* Copied libav initialize into AudioPlayer::initializePlayer() - from VideoEncoder.cc

* Used audioContext->channels and audioContext->sample_rate for play back

- MMDAI/VPVM/video/IAudioDecoder.h 2013-01-03 22:54:46.000000000 +0900

* Removed "const" due to the moved m_audioContext and m_formatContext to class member variable

- MMDAI/scripts/build.pl 2013-01-03 22:54:46.000000000 +0900

* used PORTAUDIO_REVISION = 1880 - supported OSX 10.8.2

* used LIBAV_TAG = 'v0.8.4'

* used Qt 5.0 - different for individual machine

* force to link with libportaudio.a - probably not needed

- MMDAI/scripts/osx_deploy.sh 2013-01-03 22:54:46.000000000 +0900

* directory checking to be more generic
