Tab completion not working on Kali 2.0

[Rich5]

Due to some library changes in Kali 2.0 the tab completion feature is not working with Python's cmd module which Harness relies on.

The fix actions are as follows: apt-get install python3-pip apt-get install libcurses5-dev pip3 install readline python_install.sh

The installation script will be updated in the next merge.
