Pressing Ctrl-Z while script is running causes exception

[jeffwright13]

An AttributeError occurs when I press Ctrl-Z in any of the scripts I run. line 112 of term.py isattempting to access a non-existing echo attribute in the TTkTerm class.

For example, while running pyTermTk/demo/showcase/windows.py:

$ python windows.py
Traceback (most recent call last):

AttributeError: type object 'TTkTerm' has no attribute 'echo'

This could be related to the olf library installed with pip as happened in #25 I recently fixed this echo error Still there are issue when resuming from "bg" (I don't repaint the buffer)
