I don't actually deinterlace ever but allegedly this is better than
yadif, and there's no real reason to not have this be the fallback
deinterlace when we're not using hw frames. Also change various mentions
of yadif to bwdif. Ref #12835.
- --lua and --lua-opts change to --script and --script-opts
- 'lua' default script dirs change to 'scripts'
- DOCS updated
- 'lua-settings' dir was _not_ modified
The old lua-based names/dirs still work, but display a warning.

This isn't quite as robust as idet.sh as the default detection
interval is only 4 seconds vs 35 for idet.sh. idet.sh can have such a
large sample time since it turns off the vo and uses --untimed, which
is currently not possible from lua.
