#35 Implement tab completion for bash

[Anonymous]

As requested in ft ID: 1554128 I'd like to propose to implement tab completion. Opening a new feature request as the old one was closed without any comment
It is the same for command history: wickedShell seems to have impleted its own version which hides the implementation already available by bash.

I am using wickedShell with cygwin bash so it can be tested on windows, too.
