add wav data type for audio_capture and audio_play (ros ticket #14)

[ahendrix] The patch to audio_capture looks nice and clean.

It looks like the patch to audio_play contains a lot of duplicated and dead code; is there any way to clean that up?

Can you add test cases for your new functionality?

[yoheikakiuchi] I added audio_common_wav_R1.patch.
I have cleaned up code and added test directory for launch files.

I have try to use wav file for out put, then i download the source code of audio_capture, and change the code :
ros::param::paramstd::string("~format", _format, "mp3");
to
ros::param::paramstd::string("~format", _format, "wave");
when i run the project, it get an error:
[ERROR] [1466752230.167599944]: Unsupported media type.
i try to look for more information, the return is "false" from the code :
link_ok = gst_element_link_many( _source, _sink, NULL);

Could some one kindly help me? thanks.
