All formats downloading slightly broken

[zhenyahacker]

Seems like downloading of all available formats is slightly broken due to inappropriate for very this usage output files naming.
What I mean:

youtube-dl ragWo0bX9Pc --all-formats --get-filename
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.m4a
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.webm
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4
FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4

As you can see, there is a bunch of exactly same filenames to be generated, and thus only first variant from list is really being downloaded, others are just skipped because "[download] FOUR YEARS OF MARIO MAKER-ragWo0bX9Pc.mp4 has already been downloaded".

I think it would make sense to change filename generation to add a variant/quality name to it, maybe not for any usage but for all formats execution.
