chore(ci): move over to CircleCi config

This commit gets rid of all references to Travis and, belatedly, Jenkins.
Now all CI is done on CircleCI and releases are run locally.

The CI no longer updates the docs and code.angularjs.org for jobs that are
not on the `master` branch.

During releases, the docs and code should be uploaded manually.
