[Core feature] Possibility to check for None values

[MartinTschechne]

Motivation: Why do you think this is important?

Additionally to is_true() and is_false() it would be nice to have a functionality to check whether None is returned by a task. This could be useful in conditionals for example.

Goal: What should the final outcome look like, ideally?

The function is_none() should simply return True or False and logically work like

if val is None:
    return True
else:
    return False

Describe alternatives you've considered

Either returning the string 'None' or False and explicitly check for that.
