Add footer metadata detailed guides, supporting pages and collections

For consistency I have added footer metadata to the above pages
• include partial to pages
• add footer_meta: true local to header
• nest styles for detailed guides to correct layout issues
• bumped toolkit gem version to include measurement variables used

Removing that div would leave a dvi named inner-block that's not technically an inner block once it's parent is removed. I guess it does still have a parent, just not a direct parent like it currently does.

Either way, yeah, I'll remove it.
