v0.6.0

Changed

• The command is now rest instead of term-rest-client: rest, rest -gui,
  rest run, rest load and so on. The installers (get.sh, make install) install
  rest and keep term-rest-client as a link to it, replacing an older copy, so existing
  scripts keep working; make uninstall removes both. get.sh warns when another
  program called rest comes first on your PATH. Release archives are now
  rest-<os>-<arch>.tar.gz (rest.exe in the Windows zip), and go install takes
  .../cmd/rest@latest. The product name, the data folder (term-rest-client) and
  TERM_REST_CLIENT_DATA are unchanged, so existing workspaces are found as before.

Fixed

• Browser UI: the Variables dialog listed environments as
  "[object HTMLDivElement], [object HTMLDivElement]" instead of their names, so they
  couldn't be selected.
