Signal to Create Profile on User Registration

[NeuralFlux]

Since we have a User registration form and a Profile model, what's left is to link them together. That is, create and link a profile to the user once they're registered. This may help in case you're stuck.

(What about deleting the profile when user is deleted then? Try to understand this on your own, we'll put it in the weekly tips next week!)

Expected:

users/signals.py to implement all the signal code
