Bug in gw/numhash.c

This module has a bug that causes a crash.

Replace

    if (octstr_str_compare(type, "text/plain") != 0) {
	octstr_destroy(type);
	octstr_destroy(reply_body);
	error(0, "Strange content type <%s> for numhash, operatiomn fails",
	      octstr_get_cstr(type));
	return NULL;
    }

with

    if (octstr_str_compare(type, "text/plain") != 0) {
	octstr_destroy(reply_body);
	error(0, "Strange content type <%s> for numhash - expecting 'text/plain',
operation fails",
	      octstr_get_cstr(type));
	octstr_destroy(type);
	return NULL;
    }

as you can see, the Octstr *type is referenced after it is destroyed. Also,
correct the spelling
and indicate in the error text what MIME type is acceptable.
