Add download m3u playlist functionality

[hazcod]

Still uses -file, but if it starts with http (case-insensitive) it will try to download it to the OS tempdir + telly.m3u and remove it afterwards.

Nice job @hazcod! I'll review this later today and merge - I'll also do the same to your Docker PR.

Looking good - I wonder if -m3u is a better option if we're adding URLs to the -file argument? Opinions please ;-)

[hazcod]

Perhaps -playlist? Numbers in an argument feel a bit weird to the touch.

[cesalo]

+1 for playlist.

[hazcod]

@tombowditch I renamed it to -playlist in the last two commits, let me know what you think.

[tombowditch]

Looks good. Can we add a -file that just kills telly and tells you to update it to -playlist just for legacy support - will only add it for one release and then remove it.

[hazcod]

@tombowditch , see last commit. Using -file will throw a warning and overwrite -playlist.

[hazcod]

Changed my mind, it now exits telly. If you don't shut it down, people will keep on using it.

[tombowditch]

Right, sounds good. This looks good to merge.

[tombowditch]

Is this comment relevant anymore?

[hazcod]

Indeed, warning has been implemented.

[hazcod]

I fixed it for you, should be good now. We're getting there.. ;-)

[tombowditch]

Many thanks for doing this 👍

[tombowditch]

I'll release a new release shortly...

quick question .. if this is downloading the m3u file directly from http .. shouldn't also add the comma missing (#EXTINF:0 ->#EXTINF:0,) in most of the m3u files out there like vader by default? :). Just an idea.
