re-org imports bin/ and telnetlib3.contrib
Re-write intro pages, re-org headers
support telnet url. --logfile, \n -> \r
disable fullscreen by default, not quite working

a few bug fixes also
move wcwidth to contrib
log bytes written out
allow str(client) or str(server) when unconnected
make base class ConsoleShell, TerminalShell
rename convert() to convert_cp437
export TerminalShell and ConsoleShell
pep8 fix
add force_binary for dumb servers

some servers (blackflag.acid.org) send binary text
even though they do not negotiate binary, causing
that text to be decoded as 'ascii'.
revamp setup, include pytest for 'test' argument

however I'm still struggling to get a test suite
together.
update .gitignore for distribution
remove examples folder

honeypot will become a separate project, in time.
