title: will_paginate starts next page count from 1 with indexing
body: <p>I have an indexed page of posts and it goes like:</p>
  
  <pre><code>&lt;% @posts.each_with_index do |post, index| %&gt;
     //do some rendering
  &lt;% end %&gt;
  &lt;%= will_paginate @posts %&gt;
  </code></pre>
  
  <p>While in my controller i have the following:</p>
  
  <pre><code>def index
      @posts = Post.paginate(:page =&gt; params[:page], :per_page =&gt; 15)
  end
  </code></pre>
  
  <p>The first page numbering counts up to 15 but when i proceed to page two the index count goes back to 1. I want it to proceed from 15 onwards. Thankx</p>
