[B 2.1] Send Chat message with Enter

[matrix142]

There is a little bug when you send a chat message with your enter key.
If you do this, you click on any button of the interface in the background.

This is a little bit annoying

Other behavior with chat :

Sometimes the chat repeat twice what we are writting...

The same case on 2 servers Royal Exp (my server Sweet-Lemonade and Alamort server : Fr - G3N - RoyalExp).
