Modernization megaticket

[danvk]

webdiff no longer works for me on macOS Catalina so it's high time to update it!

Things on my laundry list:

• Python
  • Fix packaging errors (error in webdiff setup command: "values of 'package_data' dict" must be a list of strings #131)
  • Get rid of README in favor of README.md
  • Format with black
  • Eliminate dependency on Flask (Don't use Flask #91)
  • Eliminate dependency on PyGithub
  • Move nose and black into the equivalent of devDependencies
  • Set up piptools for dependencies
  • Figure out how to dedupe install_requires in setup.py and requirements.txt
  • De-dupe version number between app.py and setup.py
  • Eliminate Python 2 shims (just use Python 3)
• JavaScript
  • Replace bower with npm or yarn and unbundle packages except codediff.js (Replace bower #128)
  • Use a more modern version of React
  • Convert to TypeScript
  • Format with prettier
  • Replace underscore with lodash
  • Get rid of grunt
  • Get rid of jQuery dependency (transitive dependency of codediff.js)
  • Use jest in place of qunit
• General
  • Use git to calculate diffs (Get diffs from diff #129)
  • Create a homebrew package
  • Set up testing on CircleCI

As someone who uses this tool I-don't-even-know-how-many times per day, I was extremely bummed to see that it no longer works on Catalina. Definitely would love to see it working again!

@zeptonaut Try updating to 0.15.0? It should work! Glad to hear webdiff has some loyal users :)

@danvk Working great now - thanks for this great little utility, Dan! Love how lightweight and flexible it is. I recommend it to coworkers every chance I get.
