Unable to use UUID's as permanent ids

[almilli]

DualStorage uses UUIDs as the temporary id generator. And detects the id being a temporary id as one that looks like a UUID. This means that it's impossible to use DualStorage out of the box if the server also uses UUIDs as the permanent id. I can see this being a very common use case. What ends up happening is that DualStorage never issues "remote" server commands when inserting/updating/deleting items. You should change it to use temporary ids that are something more unique instead of using a standard for real ids.

In order to get this to work, I had to override the temporary id generation and check. I just prepended a "t" to a UUID so it was a different length than a normal UUID.

    Backbone.Model.prototype.hasTempId = function() {
         return _.isString(this.id) && this.id.length === 37;
    };
    window.Store.prototype.generateId = function() {
         return "t" + uuid.v4();
    }

I like your solution and agree that this is a problem. We cannot prepend a
t and have it be backward compatible, but it will be backward compatible if
the length is still 36 characters, like if the first character was a T
rather than a hex character. If you'd like to see this in the official
repo, go ahead and make a pull request. If you run make and update
CHANGES.md, then I can accept it directly. Thanks!
