- some Do Not Track stuff
- Sparkdown macro stuff
- UPS stuff

And more!

Ok really we've got to figure out a better mode for publishing this stuff.

Return one of these from a Controller action to do nothing.

- actions may now return Generators (useful for doing piece-at-a-time
  output in CLI applications)
- Environment now handles HTTP headers
- fixes a CLI routing bug with leading slashes
- Application&env() to return current Environment

This stuff:  Still useless outside the walls of SparkFun.

Well, except the README.
