Style guide: Missing information

[FionaDyalog]

The "Style Guide" page needs to be extended to include the following:

How to enter lists – bulleted and numbered – including list items within list items.

How to start text on a new line (is there a way other than double-spaces at the end of a line, which are invisible?!)

How to enter code without it having syntax colouring and a background colour. For example, if I am writing a sentence such as:
By default, ENABLE_CEF is 1
then I want the "ENABLE_CEF" and "1" to be in APL385 font but I do not want them to have syntax highlighting and a background colour.

First two issues are addressed in PR #11

The last issue might need some thought. I've opened a new issue #12
