Shifted constants in naming and place in instr. Moved SEEDS_FILE_PATH, CRASHLOG_FILE_PATH and LOGS_FILE_PATH from commondefs.c to sharedConstants.h, since both C and Expect need these values. Also modified their names to be SEEDS_FILEPATH, CRASHLOG_FILEPATH, and LOGS_FILEPATH respectively (to match the naming convention in sharedConstants.exp). Also worked on instr's individualized log writing functionality.
