+ Improved tests on sudoers config file: **the original script have some pitfalls that wouldnt allow to run the script even if the config is vulnerable**, for example when sudoedit is configured with (ALL) or (ALL : ALL) instead of (root), which are still vulnerable configurations. In the last case, it will also break the original script because of the way the last grep was implemented, its also fixed on this version.
+ Added **test to check** if sudo **version** is vulnerable.
+ **Fixed bug** *"EDITOR: command not found" when trying to open the editor and typo in `etc/sudoers` filename.
