Add references to command modules

[bcoles]

Often command module descriptions contain HTML (which kinda sucks).

This is occasionally used for formatting, which is fine.

There are many instances where the description only uses HTML to include links.

It would make much more sense to define a references: key in the module config YAML file to contain an array of reference URLs.

The admin UI should also be updated to display the reference URLs.

We would then advise that no HTML used in description, correct?
Is there any other reason to have html in description?

Unfortunately we don't have much choice. Formatting inside the description is useful and HTML is the easiest approach.

Links are long and there's no need to have them inside the description.
