Feature request: add a remote:"never" option per save about backbone.dualstorage HOT 4 OPEN

We were discussing this here: #12 (comment)

I had also said this, which you have just shown me was an incorrect assumption:

I don't believe we need any mode that uses local storage does not mark records dirty.

Accounting for that, what do you think about having a storageMode option with these options? I'm open to suggestions on the option names. Do they make the behavior obvious?

storageMode: mode # one of: ['dual' (default), 'offline', 'remote-only', 'local-only']

from backbone.dualstorage.

I think those work ok. I can't think of a reason why I would use remote-only right now, but it makes sense for completeness. I think the names work fine if their use is documented.

I'm not sure I understand what offline is for?

I'm a little bit confused - would these used in conjunction with the "remote: false" or as a replacement? If a replacement, then I agree this is a better system - providing the decision can be made broadly at the model AND at the individual record save.

Again, I'm dealing with a weird edge case, so I hate to pollute the pool with that. But if there are other uses then making sure to have a local-only for completeness would help my case.

I will document the options regardless, but I hope to make the option names make sense without having to refer to documentation.

These would replace both the local and remote options. storageMode: 'offline' would be equivalent to how remote: false acts now: it skips the online step, makes the changes locally, and marks the records dirty. Does this table make it clear?

Yep, that makes sense!
