Allowing for out_of_bounds? code to be handled consistently #166

It would be nice to allow a way to handle out of bounds paging in a consistent way. Right now it's up to the calling code to call #out_of_bounds? and then to handle it on a case-by-case basis.

My scenario is that I want to send the person to page #1 if they happen to pick a per_page and page combination that is no longer valid:

class ApplicationController
  rescue_from WillPaginate::OutOfBoundsException do
    redirect_to params.merge(:page => 1)
  end
end

class MyController < ApplicationController
  def index
    @things = MyModel.paginate!(...)
  end
end

This would work across controllers (or views) because you wouldn't need to know about what was being paginated on, just that you needed to redirect back to page 1. Thoughts?
