Merge branch 'hotfix/3703'

THIS IS AMAZING! Normally takes me 3-4 minutes on my 4 core machine to run tests
and CS checks; with this, it took 52s. SECONDS! Thanks, @ocramius !!!!
Merge branch 'hotfix/3713'

Close #3713
Fixes #3700
Created README.md files for each component

- Since we have per-component mirrors of each component, we should have a
  README.md detailing where to create issues and pull requests, and where
  documentation lives; additionally, detailing the license is a generally good
  idea.
Forward #3721
