Markdown consistency

[ninelore]

While Markdown is very forgiving with bad formatting, we should bring the docs to a common markdown formatting standard.

Selection of issues:

• Both too many and no blank lines. There should be only one empty line between elements
• Heading order: # -> ## - > ### -> ####; No ****' as headers
• Trailing spaces
• Inconsistent horizontal line - count (common is x3)
• ...

For anybody contributing to the docs,

• Title pages should be ##, and each section in a page should be ###. : See below comment
• If making a new page, the name of it should be short and concise, preferably 2 words or less.
• ...

Page Title must be # or its another markdown violation

Heading order: # -> ## - > ### -> ####; No ****' as headers

Should this info be put in the README or a separate page for contributing info?

[ninelore]

We will put it in contributing once initial fixes are complete
