Combine the cheeky and questioning respone code

Also, fix the 'what are you talking about' response showing up if subject
or predicate was removed when checking for 'I/you/me/my/your/name'.
Avoid unnecessary spaces in catch all response
Fix when to add 'me being' in catch all response
Skip filler words in predicate
Fix assigning a String to a empty string causing no change
Handle interrogative after linking verb with subject

The question "A cat has how many legs?" was setting subject to "A cat many legs".
Fix it so that subject is "many legs" and predicate is "A cat".
