* Added `PP+exe:args` syntax
If `PP+exe:args` is specifically given, only it used.
Otherwise, `PP:args` and `exe:args` are combined.
If none of the `PP`, `exe` or `PP+exe` args are given, `default` is used
`Default` is purposely left undocumented since it exists only for backward compatibility
* Also added proper handling of args in `EmbedThumbnail`

* Enabled --ignore by default
* Disabled --video-multistreams and --audio-multistreams by default
* Changed default format selection to 'bv*+ba/b' when --audio-multistreams is disabled
* Changed default format sort order to 'res,fps,codec,size,br,asr,proto,ext,has_audio,source,format_id'
* Changed default output template to '%(title)s [%(id)s].%(ext)s'
* Enabled `--list-formats-as-table` by default
* The idea is that it should be possible to negate any boolean option by adding a `no-` to the switch
