[packman] My modified version of the youtube-dl package

[Mathias Homann]

Hi all,

I've branched and modified the youtube-dl package from Multimedia.
My modifications:

- modified the package to automatically download source tarball, gpg signature 
and version number file from upstream
- generate version number from version number file from upstream

That means that:
- a "osc service rr" which could even be done from a cron job would be enough 
to update youtube-dl to the latest released version, and that app gets new 
versions almost every day, and on some days more than one...
- the version number will follow a slightly different format now, yyyy.mm.dd.s 
instead of yyyymmdd, with .s being the subrelease and optional
- the changelog won't be updated anymore unless someone figures out a way to 
grab the changelog from git automagically.

If there are no objections from anyone, should we update the official package 
in Multimedia/ to my version?

Cheers
