Up until now I didn't see the point of using spaces for indentation.
However, the previous commit (a18bec3) was quite eye opening.
Given that python is an indentation aware language, the amount of
mistakes that went unnoticed because tabs and spaces were used
at the same time (tabs for indentation and spaces for alignment)
were unacceptable.
E101,W191 have been re-enable in the tox flake8 checker and
the documentation has been modified accordingly.

Mimic the behavior of the --color=<auto|always|never> found in tools
like `ls' and `grep'. Default to `auto' which checks whether stderr is a
tty to define whether colors are used.
Tested:
- Ran ./boostrap-vz --color=never and --color=always, confirmed
colorization worked as expected.
- Ran ./boostrap-vz --color=auto ${manifest_file} 2>bootstrap.log,
confirmed colors were not added to boostrap.log by default, repeated
the test with --color=always and confirmed escape sequences were
output.
