@descr We must support loading of different URLs with different handler or loader into different tasks simultaniously.
They call us back to return state of operation. We need some informations to distinguish
between these different "loading threads".
This is the reason to implement this dynamicly list.
@attention I maked class LoaderThreads threadsafe! Using will be easier in a multithreaded environment.
struct DispatchBinding doesn't need that!

@short base class for dispatcher implementations
@descr Most of our dispatch implementations do every time the same. They try to handle or load
somethinmg into a target ... normaly a frame/task/pluginframe!
They must do it synchron or sometimes asynchron. They must wait for callbacks and
notify registered listener with right status events.
All these things are implemented by this baseclass. You should override some methods
to change something.
"dispatch()" => should be you dispatch algorithm
"reactForLoadingState()" => do something depending from loading state ...

@short you should react for successfully or failed load/handle operations.
@descr These baseclass implement handling of dispatched URLs and synchronous/asynchronous loading
of it into a target frame. It implement the complete listener mechanism to get events from
used loader or handler and sending of status events to registered listener too!
But we couldn't react for this events in all cases.
May be - you wish to reactivate suspended controllers or wish to delete a new created
task if operation failed ...!?
By overwriting these pure virtual methods it's possible to do such things.
We call you with all available informations ... you should react for it.
BUT - don't send any status events to your listener! We will do it every time.
(other listener could be informed as well!)
You will called back in: a) "reactForLoadingState()" , if URL was loaded into a frame
b) "reactForHandlingState()", if URL was handled by a registered content handler
(without using a target frame!)
@seealso method statusChanged()
@seealso method loadFinished()
@seealso method loadCancelled()
@param "aURL" , original dispatched URL
@param "lDescriptor" , original dispatched arguments
@param "xTarget" , target of operation (could be NULL if URL was handled not loaded!)
