Give script templates access to their own name and other metadata

[anthonyrisinger]

You can access options and args via function (kingpeon.go#L68) but there is no way for a script template to discover the command that triggered it, or other useful information.

This package is used by go-jira. I'm trying to make a common entry point like so:

custom-commands:
  - name: sync
    options: ...
    args: ...
    script: |
      JIRA={{jira}} exec {{jira}}-lib sync 10<<'EOF'
      {{toJson options}}
      {{toJson args}}
      EOF

The script is the same for every custom command except for the word sync (or whatever command is in play) because I don't see a way to get that info, eg. {{.name}}.

Could we assign . to the config so things like .name or .help work? Or something else?

Adding toJson and fromJson would be great too. The heredoc nonsense above is because go-jira does not compact the JSON. Lastly, a shellquote function would be massively appreciated!

With the above change the {{.}} object will correspond to the corresponding DynamicCommand structure:

Awesome thank you!
