Title: rename @screen-XX to @screen-XX-min for clarity+unambiguity

`@screen-XX` is semi-implicitly the minimum size of an XX screen. This commit renames them to `@screen-XX-min` to avoid any confusion. Also makes for a nicer symmetry with the existing `@screen-XX-max` variables.
Does not affect the generated CSS.
