Title: Remove use of global for compatibility

global is a Sass 3.3 feature and can cause compile errors with Sass 3.2 and libsass.

If a global is required to make the iteration work, then we can define `$inuit-generate-spacing-alias` as a `null` global and still keep compatibility with Sass 3.2/libsass
