add feature for max-size file downloads

[Vile-ircN]

Could there be a flag for ignoring videos that exceed a specified file size? I know some sites http headers might not always work with this, but it would still be useful for videos where it does.

Basically I want to download a batch list file of youtube videos but skip files >20mb

Thank you

The option --max-filesize will work (it was added in #646):

youtube-dl '1ltcDfZMA3U' --max-filesize 5m
