making the UUID a first-class citizen

[cromulus]

every list and every reminder has a unique id.

This PR displays those values when --format json is used, and allows the ID to be an argument for the list and reminder.

we also return the unique ID and the list ID when a reminder is created.

Just wanted to bump this: using uuid as a first class citizen in the cli will help substantially with integrating this into other applications!

Thanks!

Another reason why having the UUID as a first class citizen: it means we can LINK TO A REMINDER

x-apple-reminderkit://REMCDReminder/{UUID is here}

FYI, the code builds and runs, and only adds a few json fields when --format json is added.

I updated the path provided here to buildable state again. See #103

I do believe it would make a lot of sense to fully switch over to the UUID based approach on the CLI as the index based access is very brittle. For the "delete completed item" that I actually wanted to solve for myself the index based approach would be weird as you need to set context information ("Should the indexed list contain completed items or not?").

I would suggest to deprecate index based access to the items.
