[WiP] Include/Exclude files and directories

Include/Exclude files and directories

- [ ] Rename the configuration options to follow the Rubocop "flavor", as recommended by @bbatsov
- [x] Remove the duplicated NoGoZone methods from my commits
- [x] Rework the relevant documentation
- [x] Update the change log
- [x] Personally I would not like to see this line in the default configuration: Excludes: [], because we're not using it. (You can include them in the documentation)
