Enable Travis build, test, deploy

[MikeTheCanuck]

Implementing the backend service pattern.

Enables the project to automatically

• build every commit in Travis
• test every commit in Travis
• deploy any test-compliant build that commits to master directly to AWS

Testing

You can test that this still works locally by running any or all of the following commands:

• homelessAPI/bin/build-proj.sh -l - should terminate with no errors - this merely builds the Docker container, but runs no code in or at it
• homelessAPI/bin/start-proj.sh -l - should finalize with a running Docker container, whose app you can browse to at http://127.0.0.1:8000/homeless
• homelessAPI/bin/test-proj.sh -l - this should finalize with all tests passing - this launches the container (builds it if the configuration has changed) and runs all configured tests

[MikeTheCanuck]

Despite the build failure "pr", this is a good result - the "pr" failure merely means the two build jobs entered a race condition on the test database.
