initialize() method only supports the "models" parameter as an array

[gbedardsice]

In the initialize method, the "models" parameter is considered an array. The thing is, in a plain backbone collection, I can do something like:

var collection = new Backbone.Collection({hello: 'world'})

and it will instantiate the collection with a single model in it.

But if I do this with a pageable collection, I get errors because an object is not expected.

This isn't actually advertised or documented. In fact there isn't a test case that guarantees this behavior in Backbone. It's just a side effect that Backbone.Collection's constructor delegates to reset which delegates to add. I don't have anything against supporting this tho, it should be fairly easy. PR welcome.

Change _.isArray to _isArray to help the minifier with name mangling.
