v2.5

Notable changes:

• Added a simple test harness, and made a handful of tests.
• bashy-core:
  • New interactive ubik, which will use one found on PATH as a last resort.
  • arg-processor: New post-process hook post-process-args-call.
• bashy-basics:
  • buildy:
    • New command buildy make-distro, cribbed from sibling project lactoserv
      and adapted for more general use.
    • New command buildy ls-files, inspired by (and based on) the git
      command of the same name.
  • New command ls-files, top-level and non-git-specific (as opposed to the
    one in buildy).
  • Renamed jbash-array to jset-array, and made major improvements.
  • New command jstring.
• New sub-library bashy-node, for Node-specific stuff, particularly help
  building and maintaining Node projects. As with make-distro (above), this
  started out life in the sibling project lactoserv. Note: This
  sub-library is fairly opinionated.
