Make shipshape/api and shipshape/proto usable through go get

[Ciera Jaspan]

This will involve:

1. restructuring our imports to be fully qualified for all dependencies of those packages.
2. checking in the generated protos
3. ensuring that there is only one package per directory. All binaries need to be in their own directory, probably a "tools"directory"

[Ciera Jaspan]

This is going to require all shipshape developers to make a directory that matches what go get expects.
mkdir github.com/google
cd github.com/google
git clone .....

Completed for the api directory.
