authme: send help hint in login.success (welcome.txt is dead)

welcome.txt isn't read by current AuthMe — Settings.useWelcomeMessage
key is absent from config and the file was empty. The post-login
message is actually login.success in messages_en.yml, which was set
to '' (silenced).

- messages_en.yml: login.success now multi-line via \n escape:
    "successfully logged in" + "type /help for a list of commands"
- welcome.txt: emptied (unused)

Live reloaded via authme reload.
