-Putting a human on purrbation gives them cat ears and a cat tail, and sends them the message 'You suddenly feel valid.'
-Removing a human from purrbation reverses the effects, and sends them the message 'You suddenly don't feel valid anymore.'
-Renamed "Long and Smooth" tail to "Cat" tail. I wasn't kitten anyone with the old name.
-Updated changelog.
Forgot to include these two in the last commit:
-Cat ears and tail now use your hair colour instead of your mutant colour.
-Added changelog.
