Enhance route command with ptables and multiple routes

This commit rewrites the `routes list` command to use ptables to present
a slightly nicer list, including a new field if the route is enabled or
not (which is quite useful).

In addition, it reworks the enable command to support enabling multiple
routes (not only one route as per removed TODO). This allows users to
actually take advantage of exit-nodes and subnet relays.
