Add Matomo as an option for analytics_tool.

[set5think]

Matomo is a Google Analytics alternative for use-cases that require all tracking data be kept internally, and is set up the same way as the existing supported analytics tools.

thank you @dirrao for the welcome! RE: screenshots, what exactly are you wanting to see? A screenshot of my debug console showing the matomo tracking code injected?

I am referring to the UI related changes.

[set5think]

Hmm, sorry for the confusion here, but there is no UI change I'm aware of with this. The html page is likely what triggered the "area:UI" tag to be added automatically. But it's just a script tag, nothing more. And this mechanism is already tested through the analytics_tool tests. Can you point out what change you're talking about that needs a screenshot? Thanks!

Some static checks and docs need fixing though
