    Ensure created symlink is in $PATH

    With "sudo", the $PATH is overriden an really basic:
    PATH=/sbin:/bin:/usr/sbin:/usr/bin
    It doesn't list the /usr/local/(s)bin, hence the created
    symlink wasn't seen by the script.

    It also push that symlink creation in the __new__ special
    method in order to make it cleaner.

    Finaly, it takes care of lint/pep8 failures, not related to
    this change (how is that even possible?!)
