start of user auth functionality
user models and forms
added registration functionality - cant log in yet LOL
login/logout functional. TODO: special characters in category name not being recognized, problem most likely with regex used
Merge branch 'auth' into dev

Added user functionality. Anyone can register and login/logout that gives users that are logged in more functionality. TODO: fix regex so that C++ is recognized as a category.
Found source of bug: \w+ only recognizes alphanumeric values, ergo a category like c++ throws an error.
Merge branch 'dev'

Second working version of Tango site. Authentication is functional, users can make new accounts/login/logout and only add categories&pages if they are logged in.
