Rob Savoye 21ed3dcdbe * monitor.c (set_loadtype_command): Fixed so it doesn't core dump.
* monitor.c (monitor_load): check the load type and load the file
	accordingly. Default to gr_load_image().
	* monitor.c (monitor_load_ascii_srec): Load an ascii file in
	srecord format by downloading to the monitor.
	* w89k-rom.c, op50n-rom.c: set supported load types.
