Summary: add data to SWF SOLO POST requests, to ensure that Flash does  
not turn them into GET requests

Details:

SWF has a bug whereby an empty POST request (one with no data in it's  
post body) is turned into a
  GET request. This behavior used to be masked by the way we forced  
all query args into the POST
body for post requests.

When a change was made to  separate  and preserve the query string  
from the post body, people
started reporting bugs where their POST requests became GET requests.

This patch forces the "__lzbc__" cache-breaking timestamp arg into the  
body of SOLO post requests.

I am wondering if I should also force this value into Proxied  
requests, to ensure that
the data which is sent to the back-end is consistent between SOLO and  
proxied requests. This
patch only forces the __lzbc__ arg into SOLO POST  requests.


Tests:

test.lzx:
<canvas debug="true" height="400" >
     <dataset name="dsGroups" request="true" type="http"  
src="test.jsp" querytype="POST"/>
     <datapointer name="dpGroups" xpath="dsGroups:/Response">
         <handler name="ondata" args="d"><![CDATA[
             Debug.write(d);
         ]]></handler>
     </datapointer>
</canvas>

test.jsp:
<%System.out.println(request.getMethod());%>
<Response>
	<Method><%=request.getMethod()%></Method>
</Response>
