My space resolution work so far. Current issues:
- no space resolution for tables, yet.
- spaces inside list-item-labels and list-item-body to properly set up for addAreas stage.
- conditional lengths on lists not checked, yet.
- block w=0 causes a fence right now although it shouldn't.
- no space resolution due to space-before and space-after caused by the line-height property (I've totally skipped that for now)
