New tools features.

  - Rename sbovcheck to sbocheck.

  - sbocheck now correctly check against version and build number and presents everything in a nice table format, much easier to read.

  - Add trkpkg to properly list non-default packages for various subsystems:
    - Slackware packages: non-stock|alien|deny
    - Non-packaged software
    - pip packages (global)
    - pip packages (by virtualenv)
    - CPAN modules (global)
    - Node.js packages
    - Vagrant plugins

  - sbocheck and trkpkg run from their own aliases (see dotfiles repo).
New sbopkg package: etckeeper. Rename other two.

  - etckeeper: new package.
  - node
    remmina:
      Just rename these two packages to the propper build-tag pattern
      (they were not LINEFEED rebuilt).
