Subject: - Updated Eye of Hellion to use the new format of the input command.
 - corrected login_fd/char_fd being uninitialized in the char servers. -
 Changed a bit around how status_base_atk works to avoid overflows. - Added a
 check to prevent using consume-delay items when you cannot use skills, since
 that opens an exploit if the item also has non-skill-casting components to
 its script.
