Title: Fix search_form_for fail to assign new :class and :id in options

This fix will make below erb works to produce correct html as below, so make Bootstrap style page works as expected.
```erb
<%= search_form_for @q, :class => "well form-search" do |f| %>
<%= f.label :device_cont %><%= f.text_field :device_cont, :class => 'input-medium search-query' %>
<%= f.label :lot_no_cont %><%= f.text_field :lot_no_cont, :class => 'input-medium search-query' %>
<%= f.submit :class => "btn" -%>
<% end %>
```
```html

Device contains
Lot no contains

```
