Tab completion

[dhellmann]

Command and file tab completion. Do not make it as complex as bash. Maybe include history and preloaded command list

The project, https://github.com/xonsh/py-bash-completion, is quite interesting as it can bring in the bash auto-completion, but not self-defined aliases.

Nice, thanks for that tip!
