Add ability to change the application's name

[tarnfeld]

At present (from what I can tell) the name of the click application is figured out automatically, for instance...

$ python app.py
Usage: app.py [OPTIONS] COMMAND [ARGS]...

If the application is a module, and the click application is invoked via __main__.py the help text is a little unhelpful...

$ python -m app
Usage: __main__.py [OPTIONS] COMMAND [ARGS]...

Is there a way of changing this, and if not could someone point me in the direction for a pull request?

You might wanna have a look at https://github.com/mitsuhiko/click/blob/f3ee4e539ef4d81a20465009ea30cc12283547c0/click/core.py#L461-L462

Ah, thanks. I was struggling to find that. Passing the prog_name argument does the trick!
