Add Drush commands

Thanks for the interest, @codi. I've actually been toying with the idea of Drush commands myself. Let's add them to Checklist API module so that all implementing modules can benefit from it. I'm the maintainer of that project, so feel free to reach out for direction as you go. I'm imagining drush checklistapi-list and drush checklistapi-show <checklist-id> commands to begin with. Is that in line with what you're thinking?

It'd be neat if we could also update task completion via Drush. Something like: drush checklistapi-update <checklist-id> --complete=task2,task4,task7

Here you are an initial innocent drush file:
- drush checklistapi-list: listing all available checklist
- drush checklistapi-status ID: show the status of a requested checklist

Thanks, @itarato! I'll take a look at this as soon as I have a minute.

I added a checklistapi-list command for starters. I refactored it to correspond to the Checklists report. It uses drush_format_table(), which is only available in Drush 6 or later. It should be in the dev build in a few hours. Feedback welcome.

$ drush capi-list -h
Get an overview of your installed checklists with progress details.

Aliases: capi-list

$ drush capi-list

I've added a capi-info command now. It should be in the dev build in a few hours. If no one reports any problems with this, I'll roll a release with it soon. Then we'll want to forward port this to Drupal 8.

$ drush capi-info -h
Show detailed info for a given checklist.

Arguments:
 checklist     The checklist machine name, e.g., "example_checklist".

Aliases: capi-info, capii

$ drush capi-info example_checklist
This checklist based on sun's modification of Dries Buytaert's Drupal learning curve is an example implementation of the Checklist API.
