chore(build): use precise-commits for formatting

[JamesHenry]

• Adds precommit hook to validate staged code changes
  • Expected workflow right now is that if the check fails in the precommit hook, you would run yarn format, restage and recommit.
• Updates formatting check for PRs on Travis
• Removes old formatting scripts

I've kept the singleQuote preference by adding a .prettierrc file, but left out the printWidth configuration as we had previously discussed reverting to the default.

Note: There is some noise in the package.json from packages moving around as it appears they were added manually in the past and were not in alphabetical order.
