Array#paginate is inconsistent with collection#paginate

Currently, Array#paginate's API is in the form of

[1,2,3].paginate(page=1, per_page=15)

whereas Rails' collections use the form

myCollection.paginate(:page => 1, :per_page => 30, :total_entries => num)

Now there's multiple issues with this:

1) using a tuple of options instead hash-style options

2) different per_page

3) Depending on the environment (e.g. test vs. development), one method can return an Array while in test or a collection in development.

I've attached a diff of what I think should allay this issue.
