New private and whisper features

New private text and mention features

For better readability and clarity we renamed:

“Send quick message” to “Mention”

and we remove the # and @ in texts and add clearly the avatar and the action of the user:

You clearly see now the avatar of the user you are sending a mention or a private text

You can however style use the shortcuts # and @ to autocomplete the user

# is for private message

@ is for mention.

This change also corrects the user of users that were containing some [SPACE] character inside their usernames.
