Release - service.subtitles.subscene.foreignonly

As I found it to be quite difficult to identify subtitles containing only the foreign parts (forced) and I had to go to subscene to set the ForeignOnly filter, search and download subtitles manually all the time, I adjusted the existing subscene subtitle addon by CrowleyAJ to search for and download only subtitles with the foreign parts.

This release does not intend to replace the existing subscene addon and does not add anything to the original addon, but is meant to be installed in addition to it. This way in the subtitle browser, users have the choice of specifically searching for the foreign only parts if there are any or use the main subscene addon to fall back to the full subtitles.

To install:
- download my repository https://github.com/AnonTester/kodi-repo/...-1.0.0.zip
- Kodi → Addons → Addon Browser → Install from zip file → repository.anontester-1.0.0.zip
- Kodi → Addons → Addon Browser → Install from repository → Wuff's Repository → Subtitles → Subscene.com (ForeignOnly) → install
- Then enable it via Add-ons → My Add-ons → Subtitles → Subscene.com (ForeignOnly) → Enable
