Added: --list-installed cli option, listing already downloaded cookiecutter packages

[chrisbrake]

This is a re-implementation of #916 since that seems to have died due to lack of test coverage.

Adds new command: cookiecutter --list

This lists locally available templates, for example:

user$ cookiecutter --list
7 installed templates:

• cookiecutter-bottle
• cookiecutter-pyramid-talk-python-starter
• cookiecutter-sublime-text-3-plugin
• cookiecutter-template
• puppet-openstack-cookiecutter
• pyramid-cookiecutter-starter
• python-macon-template

Any chance of this being merged soon?

I've not heard anything from the maintainers.

Okay. By the way, I installed this PR from source and found that when you write —list, you have to put a string in for TEMPLATE since it’s an argument. Maybe this would work if TEMPLATE was a click option? Thanks for working on this!

@chrisbrake @mikeckennedy Thank you for contribution. I updated this to last codebase version and merged to master.
It will be available in cookiecutter 2.0 or you can use it in current master.
By the way. Please, never use same variables names like build-in defaults (was list).
