Initial Steps

• [Yes] I have updated to the latest build from Jenkins before reporting a bug
• [Yes] I have checked, if the bug was not already reported by using the search.
• [Debug is too heavy] Attached is my ForgeEssentials/modlist.txt, my latest.log, and my debug.log

Describe the bug
When using p user (non-existent user), a weird exception thing shows up, instead of a proper error message.
To Reproduce
Steps to reproduce the behavior:
| 1 | Type p user KAJEWFDOJAWDOIJAWODJAWOID()()()A(W =D(UAW=D()AW)(.
| 2 | See error.

Expected behavior
A proper error message.

Desktop (please complete the following information):

• OS: Windows 7.
• Browser: Chrome.
• Version: ?
  latest.log
  modlist.txt

I think this is because the username code is sending a request to mojang if a user doesn't exist. It seems Mojang is returning a 400 error when receiving a username with this junk data.

I can fix the code to behave gracefully when this happens.

Thanks.
