Using a Mojang account to log in renders your e-mail as your username

If you use a Mojang account instead of a "legacy" Minecraft account to log in to the game, it uses your e-mail as your username in SSP. This means in death messages, chat comments (why would I be talking to myself?), even crash reports your e-mail is exposed. This is a major privacy violation considering the huge number of crash reports posted on here and on the MCF every day. This does not affect SMP because Minecraft pulls your regular username when connection to a server, however I have not tested it on LAN.
