Merge branch 'stable'
shifting dependency on lib/argparse4j to version 0.4.3.mvn, and switching to mdm-releases.com upstreams imported automatically from maven.
fix and create acceptance tests for a regression in the previous release where asking for --version or --help outside of a git repo complained flatulently.
track updates in exus-build
discard some comments so old they've got python snippets in them
another minor cosmetic feature, skip use of ansi codes when we don't appear to have a tty.
Merge branch 'master' into stable
