mplayer path not reading from CoreConfiguration Table on Windows

[Mike Rowley]

MpVideoMediaElement.MPlayerBinaryPath is not being read from the CoreConfiguration table in windows, two code changes
in the function at the bottom of this message seem to work to fix the problem.

MpVideoMediaElement.cs Change

        private class PlatformProviderWindows : IPlatformProvider
        {
            private string mplayerBinaryPath = null;

            public string MPlayerBinaryPath
            {
                get
                {
                    if (mplayerBinaryPath == null)
                    {
                        string @default = Hyena.Paths.Combine(OpenSplash.Environment.Paths.ProgramFilesX86, "mplayer", "mplayer.exe");

                        mplayerBinaryPath = ServiceManager.ConfigurationService.GetValue(
                            "OpenSplash.GUI.Controls", "MpVideoMediaElement.MPlayerBinaryPath", @default);
                    }

                    return mplayerBinaryPath;
                }
            }

            public bool MPlayerInstalled
            {
                get
                {
                    return IO.File.Exists(new Uri(this.MPlayerBinaryPath));
                }
            }
        }
