Download playlists doesn't work when a newline character is in the title

[rmkraus]

If there is a new line in a playlist H1 tag, youtube-dl is currently unable to parse out the playlist title. An example of such a playlist is here:

https://www.youtube.com/playlist?list=PLIamkchgCKVuSMFn1m8Yj2d67TyGtQxxE

This can be fixed by allowing the . in the regular expression to accept new lines by using the re.S flag. I did this in my own copy by changing line 362 of common.py to have
flags=re.S
by default instead of
flags=0
I haven't found any negative results from this, but I am not familiar enough with the code to say that there aren't any.

At either rate, thanks for all your hard work, this application is great.

Works perfectly for me. playlist regex already allows dot to match any character.
Post the full output you get when running with --verbose option.

Here is the output. Looks like I could use an update. In hindsight, that may be related.
