* Adding references to @calberti and @andorardo to syntaxnet readme.

* Morpher and segmenter transition systems and new features (quotes, punctuation, capitalization, character ngrams, morphology attributes).

Cleanup changes for syntaxnet.

* TF defines the same external repositories but with different commit and BUILD

* Fix a bunch of bazel namespace issues

@tf changed to @org_tensorflow
Tensorflow stopped using protobuf as submodule, now it's external, so use @protobuf

* Sync to master of tensorflow submodule:
  - local version of is_cuda in syntaxnet.bzl,
  - using unique_ptr in file api.

As Docker builds are layer by layer, removing cached package files in different layers do not reduce image size. To reduce image size, cached packages have to removed in the same layer i.e., `RUN` command as the packages have been installed.
