Update metadata in OFL fonts to point to new openfontlicense.org

[jvgaultney]

Describe the issue
The SIL Open Font License web site has moved from both

http://scripts.sil.org/ofl
https://scripts.sil.org/ofl

to a new location:

https://openfontlicense.org

Please change the license URL metadata within OFL-licensed fonts (UFOs, Glyphs files, etc.) to point to the new site.

Thanks for posting this, the new site is great. We'll work though this in the new year :)

This will be a pretty big, medium size, project, since it will involve updating every OFL file. Fortunately the FAQ URL isn't in the license text itself but is in the notice text above the license, so we can update it :)

I'll update FontBakery to also accept this new URL

This is a big improvement, thanks!

We should update the gf-project-template soon so all new projects will use the updated info: googlefonts/googlefonts-project-template#129
