[Feature] Paginate ordinary collections

[alexbowers]

When a collection is returned from Eloquent, there is a paginate method on it. This is helpful for API responses.

However, if your data doesn't come from Eloquent, you have to build your own paginator to get the same structure.

having a paginate method on all collections would be useful.

Currently you have to do something like this:

return new Paginator(collect());

But and pass through some options to set the URLs correctly etc.
