Description of Problem:
Having migrated my Mincraft account to Mojang, I am required to login with my Mojang-registered email address, rather than my Minecraft username. The launcher does not understand this error, so asks if I would like to play offline.
To reproduce: Migrate your account to Mojang's Identity Servers (via a section that appears on http://minecraft.net/profile) and login. Or if you have migrated, login with your minecraft username.
Error Messages:
None, but there should be a message asking the user to use their email address to sign in, rather than their minecraft username.
Error Log:
2013/06/01 10:41:23 [sEVERE] Unknown login result: Account migrated, use e-mail as username.
