Improve variables

[robinpoort]

Each variable should be used only once outside of other variables.

Incorrect

variables/_type.scss
$line-height: 24px !default;

mixins/_content-block.scss
@mixin content-block($spacing: $line-height, $location: bottom ) {}

Also see:

illusion/scss/tools/mixins/_content-block.scss

Line 3 in d4f32f8

@mixin content-block($spacing: $line-height, $location: bottom ) {

Correct:

variables/_type.scss
$line-height: 24px !default;
$content-block-margin: $line-height !default;

mixins/_content-block.scss
@mixin content-block($spacing: $line-height, $location: bottom ) {}

In short, do not re-use variables directly on other elements they are meant for but use a middle-variable instead.
