Add cmd2 to Command-line Application Development section

[tleonhardt]

What is this Python project?

cmd2 library for interactive command-line application development

• The goal of this project is to make it quick and easy for developers to create feature-rich interactive shell applications

What's the difference between this Python project and similar ones?

• Applications created are full-featured shells in their own right with ability to call shell commands, redirect command output, pipe command output to shell commands, etc.
• Superior tab-completion capabilities, especially when using included argparse decorators
• Both Python and ASCII text application scripting is built-in
• Ability to run non-interactively for automation purposes

@vinta Hey Vinta, first off thank you for creating such a useful service for the Python community.

My understanding is that issues usually merge in once the thumbs-up votes reach 20. This issue has met that criteria. Is there anything further which needs to be done?

Thanks!

@vinta Can we please re-open this? We had 23 up-votes. I think this should have merged other than gone stale. And I 1 hour time between a stale warning and closing seems a bit tight.
