Test a GitHub web hook by fixing a typo in the README.

Just testing a web hook.
Update README.md, add CONTRIBUTING.md and run folders

Run folders are there so someone doesn't have to manually create them to
follow our instructions, they are excluded in the .gitignore so any
modifications in those should not be recorded by Git.
