"Fix "t->c->value.argSize == func->parmTotal" Assertion in Scripts, #303" had broken old savegames because the script checksum (idProgram::CalculateChecksum()) changed, see #344. This is fixed now, also the BUILD_NUMBER is increased so old savegames can be identified for a workaround. Don't use this commit without the next one which will further modify the savegame format (for the new BUILD_NUMBER 1305)
