(ioq_gets): Support telnet line termination "\r\n". Previously,

string input other than through parse() or getele() failed to strip
'\r', which could end up in ship names and such.
(getele): Code dealing with '\r' is now redundant, remove.  It ceased
to work in rev. 1.6 because input filtering replaces '\r' by '?'.
