Changes the name of our spacing variables due to the prefixing -/_
meaning private in the use of new "use" rather than include.
All now modular too, so all variables/mixins are accessed via their
package.
Also renamed variables file to vars for simpler/cleaner access/writing.
eg. '$-m' is now 'vars.$m'
Moved export templates elements into their own folder for better
grouping of logical usage.
Within the base export template, added some body classes to allow easier
targeted customisation via custom head css.
Split content of export templates into smaller partials for easier
future customization.
Closes#3443
- Removed different PDF template used on pages.
- Updated export view files to have the intended format passed.
- Shared the export CSS amoung the export templates.
Should hopefully address #1886
