lets not put garbage data in the client chat, as we're about to hook it up
rm unused windowChanged function in client
quiet shader class
hook up chat send button to actual sending, seems to send and receive

from the server just fine. also, as i encounter things that i can, i
am gradually changing to qstring, like id id here with sendChatMessage
prefer qstring for server chat..less conversions
implement chatsender value in server packet..hooked in from client side

needs to be hooked in from server side still.
