 * modified behavior of '.repeatEvery' modifier of each action in CoreApplication - now the 'repeating thread' is removed after the loop ends (or if another .repeatEvery action with the same name is executed)
 * added the possibility to have RMIAlgorithm (client) with multiple threads:
   - the orig. RMI algorithm renamed to RMIAlgorithmOriginal
   - the actual connection to RMI server now encapsulated by RMIMethodExecutor
   - the new RMIAlgorithm manages a queue of RMIMethodExecutors, but by default it has only one connection (single thread)
   - new RMIAlgorithmMultiThread extends the RMIAlgorithm using multiple threads (and multiple connections) used in round robin manner
 * version updated to 2.8.5
