Update: Add additional specifications and documentation pages, focusing on Featureless Make.

Just like with the previous commit (5d48ca4ffa2fd31c3ae76505c030c5f0735c2c18), this is a quick and rather brute force documentation change set.
I did not focus whatsoever on the styling and I imagine there is a lot of room for improvement.
I will likely only care about improving this once I begin work on the Context Markup Language I plan on writing in the future.

Fix other problems as observed.
