Player not resuming when the current file fully load

[ubugnu]

Whenever the play arrives to a limit where the current loaded file has not finished loading, it stops and doesn't resume. I tried tweaking with this:
if(!player.isPlaying()) player.play();
when the loading has finished, but it seems to repeat some tracks and even merge two playings

I've witnessed this problem of merging two songs before the first is finished. It seems to happen more often when the browser XHR thread is contending with other browser activity, or when the server is network-pegged. It also seems to happen more with Firefox than Chrome.

The fundamental issue here is that that song sections need to be reloaded in the face of error events on the XHR request. https://gist.github.com/mojaray2k/6619426 shows how you can grab file size for a completed XHR download, but Gapless would need a request manager to process and manage state for any errors that come up during the XHR download attempt, so it could retry.
