* OggFromWebMWriter: rewrite (again), reduce iterations over the input. Works as-is (video streams are not supported)
* WebMReader: use int for SimpleBlock.dataSize instead of long
* Download Recovery: allow recovering uninitialized downloads
* check range-requests using HEAD method instead of GET
* DownloadRunnableFallback: add workaround for 32kB/s issue, unknown issue origin, wont fix
* reporting downloads errors now include the source url with the selected quality and format
