Adjust writing rate to the baud rate

[mpergament]

The consoles have a 32 byte buffer, this gets overwritten when you go
more than 9600b/s.

I think this is a good idea, but I would suggest a few minor enhancements to the implementation.

1. If the user specifies a command-line baudrate option, that value isn't currently being passed to the Telnet object during initialization.

2. Check to see if the user explicitly set the baudrate to 0. In that case, avoid divide by zero exception and do not sleep between writes.

3. Make corresponding changes to the SecureShell object's write() and rawwrite() methods.

1 and 2 done. I am not sure I understand what you want in 3 though.

Thanks @mpergament. Your code was used in while merging netconify in PyEZ.
For telnet and console connection please use PyEZ from now onwards. refer
