adding downloadable flag to library list cmd

[rhhayward]

Hi @mkb79,

I've taken a stab at adding a "--downloadable" flag for the library list command. I tried to duplicate the pattern of the existing "--resolve-podcasts" flag, but if there's a better way please let me know. I also had to add "customer_rights" to the response_groups list to populate the necessary field for the is_downloadable() function.

I also haven't tested this with podcasts, or other types of resources, so if there's tests you'd suggest please let me know.

Thanks, rhhayward

@rhhayward Thank you for your pr. I'll review this now. Please give me some time.

@rhhayward Your code works. But instead of adding a downloadable flag we can add a filter option. So a user can select one/multiple predefined filter keywords like downloadable, not downloadable, author. What do you thinking about this?

[rhhayward]

Sure, I can do that. Here's what I'm thinking:

@click.option('--filters', multiple=True)

and then I'll create flags based on the contents for downloadable, not downloadable, and author=<Name>, and filter by those. Let me give that a shot, and if you want to revise any of the flag names, or how they're handled, let me know.

@mkb79 - I've changed to the --filter format. Let me know what you think.
