Title: Support for async (XHR) background requests 

which should not trigger the 'please wait' indicator.

This feature enables you to use the Echo communication infrastructure to request i.e. Autocompletion
proposals from the server without triggering the blocking please wait indiciator after 100ms.

When redefining an eventType from 'eventType: fooBar' to eventType 'eventType: async_fooBar'
echo will not show the waitIndicator and block the application while the server processes the event

See Echolot / Autocompletion Sync for an example
