[SDL] problem with using socket from SDL_Net SDLNet_TCP_Accept

Don't call SDLNet_TCP_Accept() a second time...you are sending on the 
first socket still, but the reading portion of your code throws it away 
(without closing it) and waits for a second connection, instead of 
reading from the first again.

There are other bugs in the program, but if you get rid of the second 
Accept and keep using the original somecomputer value, it gets to the 
scanf("%s") call.
