docs plugin

• Added a command to textual cli to run a textual app.

You can now run an app like this:

textual run basic.py

Where you may previously have done this:

python basic.py

Why? Well it allows setting things from the CLI which previously you could only set via env vars. Not everyone knows how to set env vars, particularly on Windows, and I don't want to have to educate people.

It also allows for a little less boilerplate in examples in docs. i.e. we won't have to repeat this:

  app = MyApp(css_path="app.css")
  if __name__ == "__main__:
      app.run()

• Added a mkdocs extension to insert SVG screenshots in docs.

Screen.Recording.2022-05-23.at.17.29.54.mov

• Added a "headless" mode for the above, so we don't need to take over the terminal to get screenshots

Just using this file as a test for now.
