Hi,
First of all: thank you for this nice framework, I use it since 3 years and I like it !
A few months ago I needed this feature on a project where I extend spectre for a custom starting theme for Drupal 7/8 so I created a new file that provide columns order functionalities:

- add classes from "order-1" to "order-12" to order columns on different pages
- add classes for every breakpoints defined in spectre to change columns order, i.e. "order-md-1", "order-md-2" or "order-lg-1", "order-lg-2", etc.

**Remarks**: using both order-N and order-BP-N (where N is the column number and BP is the breakpoint abbr.) on the same element does not work as order-N take advantage on order-BP-N

If you want to include it in spectre...

Added empty line before  media declaration
