Fixed UNIRIO name - Added 'uniriotec' domain also from UNIRIO

I study Information Systems at UNIRIO here in Brazil and the univesity name from the txt file was not complete.

Also I added the domain "uniriotec" which is the one used by students of "Exact Sciences and Technology Center", more information can be found on their website (http://www.uniriotec.br/).

It's exact the same university but the email domain is different for courses in this center. I just added as a "new one", don't know if I should do differently.
