Fixed bug 1673 - BEXT wave files only have extra metadata that you ca…

…n easily skip through bill In SDL_wave.c, BEXT wave files with "bext" instead of "fmt " are choked on if (chunk.magic != FMT) { SDL_SetError("Complex WAVE files not supported"); was_error = 1; goto done; } BEXT files http://en.wikipedia.org/wiki/Broadcast_Wave_Format actually playback the same as regular waves. All they have is (A LOT OF) extra header info. To open them, just SKIP the "bext" chunk, and the "fmt " chunk will be a couple of hundred bytes later. The "fmt " chunk is also bloated, but if you skip past the extra information to the "data" chunk, there is nothing different about a BEXT wave file than a "normal" one. You can then load the data and proceed as normal.
