+* Errors in playlist extraction should obey `--ignore-errors`
+* Fix bug where `original_url` was not propagated when `_type`=`url`
+* Revert "Merge webm formats into mkv if thumbnails are to be embedded (#173)"
+    * This was wrongly checking for `write_thumbnail`
+* Improve `extractor_args` parsing

If `--no-video-multistreams` is used, all formats with a video stream except the first one are ignored. Similarly, if `--no-audio-multistreams` is used, all formats with an audio stream except the first one are ignored. For example, `-f bestvideo+best+bestaudio` will download and merge all 3 given formats. The resulting file will have 2 video streams and 2 audio streams. But `-f bestvideo+best+bestaudio --no-video-multistreams` will download and merge only `bestvideo` and `bestaudio`. `best` is ignored since another format containing a video stream (`bestvideo`) has already been selected.
