20846	Increase contrib.auth's User.username length	ivoras@…	nobody	"Currently, contrib.auth's User model sets the username field's max_length at 30, the same as for first_name and last_name. This is reasonable but a bit conservative (http://www.kalzumeus.com/2010/06/17/falsehoods-programmers-believe-about-names/). Nowadays it is common to use e-mail addresses as usernames (especially if using external auth sources such as OAuth), but while the email field is reasonably long (75), the 30 characters for the username seems too short for modern sites.

I'd actually like to propose increasing all the naming fields (username, email, first_name, last_name) to 150, but I'll settle for making the username field as long as the e-mail field.
