paramsPrepareParams stack should execute checkbox interceptor earlier

The current paramsPrepareParams interceptor executes the checkbox interceptor late in the chain, which results in the 2 params interceptor not applying the same parameter set if there are checkboxes.
Instead, it should look like :

<interceptor-stack name="paramsPrepareParamsStack">
<interceptor-ref name="exception"/>
<interceptor-ref name="alias"/>
<interceptor-ref name="i18n"/>
<interceptor-ref name="checkbox"/>
<interceptor-ref name="params"/>
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="prepare"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="modelDriven"/>
<interceptor-ref name="fileUpload"/>
<!-- BAD <interceptor-ref name="checkbox"/>-->
<interceptor-ref name="staticParams"/>
<interceptor-ref name="actionMappingParams"/>
<interceptor-ref name="params"/>
<interceptor-ref name="conversionError"/>
<interceptor-ref name="validation">
<param name="excludeMethods">input,back,cancel</param>
</interceptor-ref>
<interceptor-ref name="workflow">
<param name="excludeMethods">input,back,cancel</param>
</interceptor-ref>
</interceptor-stack>

The additional bonus is that you get rid of stupid OGNL exceptions trying to set _checkbox* parameters during the first params execution
