- [settings][generic][objects] breadcrumbs, `.link--go` and `.link--back` now has variables instead of content; changed `separator` to `delimiter`
- [mixins][functions][generic][objects] renamed `font-class()` mixin to `font-size-class()` to avoid naming collisions
- [settings] renamed `micro` text to `tiny`
- [function] added missing newline
- [mixins] `font-size-class()` mixin now accepts `$line-height` parameter, passed to inner `font-size()` mixed
- [generic] disabled line-height for `text--` since it's anyway always = default
