Parcel has been removed since we didn't need it anymore (Tailwind
does the purging by itself anyway). Instead, we've told Express
to serve all static assets from src/assets/ and use twig templates
from src/ directly.
Meanwhile, Nodemon now watches for changes in .css and .twig files
too!
We'll start sending out the email in the next step, when the setup
of nodemailer is complete. Right now, everything else works:
creating a verification link, processing it when clicked on, and
even updating (instead of appending) a pledge when the same email
submits multiple times. No pretty error messages though; that's
another thing to be worked on :P
WARNING: Don't deploy this commit live; people will be told about a
verification email but they won't actually get it yet!
