`params` and `opts` are not currently passed through when using the
`#refund` helper on `ApplicationFee`. This was an omission on the
original refactor to use the new endpoint, and wasn't an intentional
design.
Fixes#386.
Follows up the patch in #351, which I now believe is wrong. The trouble
is that we were mutating the application fee object, when in reality an
application fee refund is actually a completely new resource (see
[creating a refund][create-refund]). This patch edits the original
attempt to cut a new object and updates tests accordingly.
Once again, related to stripe/stripe-php#208.

As discussed in #325, this deprecates the public visibility of
`#refresh_from` (by renaming it). It also adds some deprecation
infrastructure to produce warnings when it's used.
Usage on a top-level collection:
```
Stripe::Customer.list.auto_paging_each do |customer|
puts customer
end
```
Usage on a subcollection:
``` ruby
customer.invoices.auto_paging_each do |invoice|
puts invoice
end
```
We've also renamed `#all` to `#list` to prevent confusion ("all" implies
that all resources are being returned, and in Stripe's paginated API
this was not the case). An alias has been provided for backward API
compatibility.
Fixes#167.
Replaces #211 and #248.
