Convert web scraping task(s) to use REST API

[tangledhelix]

Particularly in make_project.py, anywhere that an HTML fetch & parse is happening, try to use the REST API instead.

• pgdp_login() can likely be replaced by a function to create an HTTP session to the API
  • If not then a new function to do that should be added
• Rewrite scrape_project_info(). Currently it is responsible to grab:
  • Book title
  • Author
  • Forum link
• Look at download_text(), download_images() and see if API replacements exist

GET /projects/{projectID} will supply:

• title
• author
• comments which could be interpolated into README.md during rendering

I don't see the forum link in the output. No other API calls seem like they'd have it either.

I see no API calls that could fetch the text or image files.

Does the API key let you into the web site as well or only into the API methods?

Auth is via a header X-API-KEY with a value of the key.

Implemented the API in make_project.py to fetch the title, author, comments. Still need to scrape to get the forum link. Added project comments, previously this was done by hand.

Nothing else to do here unless/until the upstream API has the forum_link as well.
