Add Dwitter data and some initial scraper options rileyjshaw/rileyjshaw.github.io

I love the tidal wave of projects on /lab,
and I want to emphasize that for v3.0 of the website. I update pages
across the web daily; Glitch, Codepen, gist.github.com, Dwitter,
Hackster, etc. Plus there's social media…

I'm okay with manual curation for the most part, but for websites like
Dwitter where contributions are inherently unpolished / untitled, it
doesn't make sense for me to hand-pick and manually update a giant
list.

Also: I'm not sure how long Dwitter will be around for. Periodically
saving the underlying code / images / etc. gives me more ownership
over the presentation and preservation of my data. It changes my
relationship with these sites from content hosts to publishing
platforms. That makes me feel more secure with my zillion links.

TODO(?): Automatically fetch new content during the publishing step?
