UX: Add more aliases

[hansfn]

Currently there are aliases for half of the commands. I suggest adding for all them.

I'm also thinking about making a Bash completion file. That would of course make aliases less important ...

Your thoughts?

I'm all for improvements! I think Symfony provides a helper for bash completions. Or there is some package that lets you generate it

https://github.com/stecman/symfony-console-completion seems to do the job, but it might be overkill for a small application like drupalorg. Maybe creating a simple, static bash completion file is enough/better?
