Revert "switch from portaudio -> libao"

This reverts commit 8972e877654434b87532945506f0c5eb57073e24.
Now working on gcc4.8, x86-64 on windows

Had to make my own portaudio and rtl-sdr binaries. The available
packages weren't compatible somehow.  Also wxWidgets wxPack doesn't
include OpenGL support but it's easy enough to compile.
