v2.5.0: Build reporting less compile issues

[mcrawshaw]

Due to updates in the less dependency some math operations are more strict (https://github.com/less/less.js/releases/tag/v4.0.0).

Steps

Build semantic

Actual Result

[PluginError: Error evaluating function `unit`: the first argument to unit must be a number. Have you forgotten parenthesis? in file ./semantic/src/themes/default/globals/site.variables line no. 393] {
  stack: undefined,
  type: 'Argument',

}

Version

2.5.0

Recommendation

There are a couple of updates needed in the theme less files. Wrap division expressions in parentheses and variables prefixed with negative signs must also be wrapped.

For now ... maybe: npm install [email protected] --save-dev ?
