Exercise 2b: Add support for other tags

Do some research on standard HTML tags, and add support for another one of your choice.

• (Hopefully) easy choices: anything that just alters the appearance of the text, e.g. font color.
• Slightly harder: support the horizontal rule, hr, or the ul and li list tags.
• Medium choices: change the title bar of the browser window when it finds a title tag. (Hint: this will probably involve adding another function to the Browser class which you'll call from the Renderer class).
• Very hard choice: add support for img src which will include pictures on the page. This will likely take several hours even if you're a Python wizard. You'd need to do this:
  1. Get an absolute URI to the image (see the existing code in link_clicked which does the same)
  2. Download the image file using requests, perhaps into a NamedTemporaryFile
  3. Use create_image on the canvas to draw it.
• Another very hard choice: the blink tag. This will require you to set a timer to re-draw the page periodically.
• Impossible choice: anything to do with page layout. Don't attempt to support tables, frames or anything fancy like that. It would take hundreds of hours - it's all very complicated. Don't even try.
