First round of cleanup to start release 1 sprint.

- Add deps.bzl (properly depend on python)
- Add license rule for entire package.
- Update checker_demo to account for bazel fixes to UTF-8 support
- Add some missing copyright notices

There is certainly more to do. I am breaking work into either logical
or 1 day chunks.
