New Safari Browser and Google Webfonts

[marcwieland95]

See https://github.com/mnater/Hyphenator/issues/239
Not just in Hyphenator, also in Hypher this bug occurs.

This is a bug in Safari and will be fixed in a newer version: (https://bugs.webkit.org/show_bug.cgi?id=150329)

The vendor-prefix in -webkit-font-variant-ligatures: no-common-ligatures;is no longer supported in Safari 9.1. And, sadly, the bug is still there.
Use both, the prefixed (for Safari < 9.1) and the unprefixed (for Safari >= 9.1) property:

-webkit-font-variant-ligatures: no-common-ligatures;
font-variant-ligatures: no-common-ligatures;
