Special paths defined in conf.toml

It's possible to define in configuration the paths for which we
want a special behavior:

* "not-enter": don't list the content - useful for slow devices
* "enter": list the content even if it's a link (to a dir)
* "hide": don't show the file or directory

Exemple configuration:

```
[special-paths]
"/media/slow-backup-disk" = "no-enter"
"/home/dys/**/useless" = "hide"
"/home/dys/my-link-I-want-to-explore" = "enter"
```
