UltraRogue: fix crash when restoring. The r_flags field in struct room was being written as an int and read as a short. This caused the restore functions to receive the wrong data, usually an impossible string length, and abort. This breaks save compatibility, though the save files had problems anyway: the r_fires field should have been used, instead of reading and writing r_flags twice.
