When building NDS Labs manually, a bunch of sed commands populate the env var defaults. One of these env vars is the UI's build date and version.

The idea used to be you would perform the build and, if necessary, commit the new version/date up after the build succeeds. With the advent of migrating our images to be produced by automated builds on DockerHub, I will need to come up with a better scheme for storing / generating the build date that plays nicely with DockerHub automated builds.

This ticket is complete when the NDS Labs UI image's version / build date fields are properly updated once more.
