Add Bullet train (TGV) and Monorail as "Mode de transport"

[simeoncapy]

I think adding a TGV icon could be good (and easy, since the logo already exists) for connection on stations.
The monorail is more for another network since it doesn't exist in Paris (maybe OrlyVAL?), so a logo has to be found I think.

Yup! Definitely have to look into these.
