Command aliases about click

[douglarek]

@sampsyo IMO, alias should be a part of a tool( such as git, hg), not CLI(such as click).

And I like the way git handles:

git config --global alias.ci "commit"

then you can call git commit by git ci.

This is something that is too tool specific but I added an example of how it can be implemented: http://click.pocoo.org/advanced/#command-aliases

Awesome! Thanks for the example.
