New PortAudio Driver

Once again, after upgrading my LMMS, I had to fix the portaudio DLL to prevent it from crashing at start. Every time, I replace it with the one from here: https://code.google.com/p/portaudiosharp/.
This page says:

> These bindings provide a `PortAudio` class which maps directly the PortAudio.dll methods, and a simplified higher-level `Audio` class.

> This library requires .NET 2.0 or the latest version of Mono and doesn't use "unsafe" code. Should work on any platform supported by .NET or Mono, including Windows, Linux and Mac OS X.

**So, why not use it?** After searching this repository and Google, I find that I am not the only one with this problem. They provide the source, a debugging setup, and a pre-built DLL. The Windows compiled binary is compatible with ASIO, DS (Direct Sound), and MME (Multimedia Extensions), which is all that is really needed.

I am using Windows 8 Pro 32-bit with a horrible Sigmatel integrated laptop sound card but using Microsoft's standard "High Definition Audio" drivers. The Sigmatel ones from Dell don't work with Windows 8. I think that it is sad that LMMS does not work with the standard and most up-to-date audio drivers from Microsoft. Every other DAW program I have works fine with all three major audio drivers (ASIO, DS, and MME).

The issue names no LMMS files or tests. Start by reviewing the linked PortAudioSharp source and its Windows DLL support, then compare that with LMMS's current audio-driver behavior. Done means a replacement driver works with ASIO, DirectSound, and MME without startup crashes.
