Update docs (#100)

* add CTCP ACTION information to man page

* add documentation for <message> parameter to commands which support it

* fix incorrect flag character for real name option

* add verbosity option (-V) to man page

* separate flag options in usage information

Usually the format '[option1|option2]' means EITHER 'option1' OR
'option2' may be specified, but not both. Since the options '-v', '-V',
and '-e' can all be given (and are all optional), the proper format is
'[-v] [-V] [-e]'.
