Additional commands: EOL delay, lower to upper translation, added mark parity

Added command line options:
-O, --eol-delay to have a separate delay for end of line
-U, --upper to enable translation of lower case alpha to upper case

Added ability to set mark parity.
Added ctrl-t U key sequence to allow enable/disable lower case alpha to
upper case during a session.
Updated Man page with command line options, ctrl-t sequences and
configuration file options.
Updated README.md, with above information.
