cmds.projects.CmdCreateFile: Add more options

- Add an additional, more generic value that --format understands:
    "tmpl". If chosen, the template selected by the new option
    --template-name is rendered by replacing --field key=value pairs.
  - This commit also adds the option --quote, which makes the
    renderer enclose the rendered variable values in double quotes.
