Fix MSG_Read*String*() functions not being able to read last byte from message
This is exact root of q3msgboom bug http://aluigi.altervista.org/adv/q3msgboom-adv.txt Unfortunately, server still need this ugly '1022 char limit' hack to support unfixed clients in some degree. And as it affects MSG_ReadBigString() - unfixed clients can still be crashed by 8191-chars long configstrings that comes with gamestate
