options: change path list options, and document list options

The changes to path list options is basically getting rid of the need to
pass multiple paths to a single option. Instead, you can use the option
multiple times. The old behavior can be used by using the -set suffix
with the option.

Change some options to path lists. For example --script is now append by
default, and if you use --script-set, you need to use ":"/";" as
separator instead of ",".

--sub-paths/--audio-file-paths is a deprecated alias now, and will break
if the user tries to pass multiple paths to it. I'm assuming that if
these are used, most users will pass only 1 path anyway.

--opengl-shaders has more compatibility handling, since it's probably
rather common that users pass multiple options to it.

Also document all that in the manpage.

I'll probably regret this later, as it somewhat increases the complexity
of the option parser, rather than increasing it.
