Squash tables

The space to content ratio on tables on mobile is a little distorted.
We have now moved to a more vertically compacted table layout to allow for this.

## Notes
I am using a new table-baseline unit as having `($gs-baseline/3)+4` made it really hard to actually know what was going on. 

I am not sure if we are going to be using smaller units else where, but if so, we might want to abstract this.
