Pause / Resume functionality for streaming sounds causes fail with AL.INVALID_VALUE #82

To reproduce: run Alpha-2 sample, go to the Play state, use Esc to pause and the resume the background sound.

Confirmed on Windows and Linux targets (also by others).

I have traced this to the flush_queue call (https://github.com/underscorediscovery/snow/blob/master/snow/modules/openal/sound/ALStream.hx#L106) which sets the AL error flag, but it is not checked before the update_stream call later: https://github.com/underscorediscovery/snow/blob/master/snow/modules/openal/sound/ALStream.hx#L131

I don't know enough about OpenAL to suggest a fix, but it seems that you cannot unqueue unprocessed buffers which seems like what the code is doing (OpenAL spec 1.1 section 4.3.6). But I lack the bigger picture :)

Have you seen this after snow alpha-2.0 at all?
