Adding "--parent" option to create-issue command

[pedropb]

Adding "--parent" option to create-issue command, allowing sub-tasking.

I created a PR for this before, but it was bugged when the command was issued without --parent option. I used the same workaround that was already presented in the code for --parent option of create-project command.

First of all, many thanks for contributing to this project! I really appreciate this!

Your PR looks very nice. However, to keep consistency, when adding an option to "create-issue" we should provide the same option for "update-issue" as well. Could you please also add the option and implementation for "update-issue"?

Furthermore, at the moment there is no way to display the parent task. When we add a new option for attributes the user needs to be able to see this attribute when printing an issue.

Please take a look at template/issue.tmpland add the "parent task" information at a nice place.

I'm working on it!

@a11n, what do you think that works better:

Redmine style

Property style

@a11n, the current branch listed on this PR implements the Redmine style template.

I'm done! You can merge it any time now.

Hi @pedropb ,

I saw you started your own project based on this. Just want to tell you the I'm totally sorry that I never found the time to merge your nice PR. Since today it's on my TODO list, but unfortunately I never found the time to do it. SORRY!

I will deprecate this project and will notify committers to contribute to your project. Wish you good look with your CLI.

Thank you,
André

No worries @a11n!

I thought you wanted to keep things separated. I understand your tool has a very specific goal which is to provide a CLI for redmine API.

My need was for an automation tool (like batch generation of issues, relations etc.). So I hacked your tool to add that functionality. It I totally think both tools can coexist and serve different purposes.

It is hard to find time for these hobby projects!
