In another change, I've added an npm dependency to Djblets to install
babel-plugin-dedent, which allows us to use ES6 template strings without
filling our compiled output with a ton of ugly spaces. This change enables it
for Review Board as well.

  • Ran setup.py develop and saw babel-plugin-dedent get installed correctly.
  • Used the dedent tag in extension code.
