Enhance options of enqueue() method

[Deleted user]

The enqueue method of Queue class should be enhanced the following way:

• enqueue(action: Function, dateToExecute?: Date, options?: IQueueEnqueueOptions): dateToExecute, the time when action should be executed
• enqueue(action: Function, millisecondsBeforeExecute?: number, options?: IQueueEnqueueOptions): millisecondsBeforeExecute, the time in ms to wait, before action should be executed
• enqueue(action: Function, optionsWithTimeToWaitValue?: IQueueEnqueueOptionsWithTimeBeforeExecute): one of the upper values, submitted via optionsWithTimeToWaitValue object
