change dialog edit of the torrc to `vitor`

https://github.com/nyxnor/vitor

It is like visudo/vidoas but for the torrc. It copies the torrc to a temporary file, lock it to not be edited on another instance. Than it lets you edit with your favorite editor. After saving and closing the editor, the file will be verified with tor --verify-config -f FILE. If okay, save it, if not, let you choose between e (edit again), x (exit without saving), Q (quit and save changes DANGER).

Main reason is preventing people from using an invalid configuration on the torrc because it can break tor as not starting again.

It can be installed from git or build the debian package from source. Has manual and video demonstration.
