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.

No longer passing anything through the main thread which was causing
audio and IQ interrupts on UI events -- hopefully improves OSX jitter.
SDRThread can now have unlimited Demodulator bindings.. :)
