Improved conditions logging in errors and first experimental waiting hooks

• improved error messsages
  • now condition in Should method will be rendered like:
    ... .Should(Be.Visible) over just ... .Visible
• deprecated SeleneElement#config, use SeleneElement#Config instead (same for SeleneCollection)
  • yet be attentive... the fate of keeping SeleneElement#Config as public is also vague...
• added experimental feature: Configuration._HookWaitAction
  • prefixed with underscore implies that this feature is kind of "publically available private property that might be changed/renamed/removed/etc in future;)", so use it on your own risk!!!
  • by default equals to null, making internally call waiting algorithm for actions as it is, without additional customization
  • specified to something like:

    Configuration._HookWaitAction = (entity_object, describe_computation, wait) => {
        Console.WriteLine($"STARTED WAITING FOR: {entity_object}.{describe_computation()}");
        try
        {
            wait();
            Console.WriteLine($"FINISHED WAITING FOR: {entity_object}.{describe_computation()}");
        }
        catch (Exception error)
        {
            Console.WriteLine($"FAILED WAITING FOR: {entity_object}.{describe_computation()}");
            throw error;
        }
    };
    

    • should provide some additinal logging for all Selene actions, called on entities (like SeleneElement, SeleneCollection)
    • under actions we mean "void commands" not "queries returning result".
      • void command like element.Should(condition) will return the element itself instead of void ;)
