The flash transport to support RPC for IE7 has problem with multiple gadgets in a single container

The flash rpc transport to support ie7 does not work properly for multiple gadgets in a single container. The function flushHandshakes in flash.transport.js only called by ready() function which only be called once by the flash component after it initialized itself.

The flash component act as singleton to make sure the main function only called once for a page. The transport ready() function which called at the end of the main function of the actionscript file hence only called once even though multiple gadget call gadgets.rpc.setupReceiver().
So if a second gadget is in the same container, the flushHandshakes() will never be called to setup that gadget iframe.
