Phone numbers in Brazil have now a 9th digit

UPDATED

Now, only the number 9 (nine) is accepted. Look at the DDI rule.. I had to remove the optionality to put a space after the number, 'cause it was accepting numbers like '12345-6512' (without the space, the \d{1,3} was allowing it).

Hey, guys.. I was checking this plugin and I realized that it's only considering 8-digits numbers, but now São Paulo has 9-digits numbers. This rule will be applied to other states in Brazil soon, so I made the changes just to accept an extra digit.
