[Forge] Don't send resets to Clients which are known to not support it

Don't send the reset packet to Forge clients which are known to not support it. This does prevent the crash of Forge Clients which have a build number under 1209. This also prevents Forge Clients under that Buildnumber from joining any other Server (which is a Forge Server) when they don't support resetting the Handshake.
Why do you need to reset the Modlist when it never has been transmitted ? Have i missed something in Forge ?
