Fix further crashes when following dgamelaunch games. The crashes apparently resulted from reading a ttyrec header and then trying to read the data chunk before dgamelaunch produced it. When the data chunk did become available, it would be read by the header function. The simplest solution was to store the position for reading the ttyrec file in the DGLSession, and to leave it unchanged if anything unexpected occurs when reading.
