Add option to change train name in Train lines manager

With the notifications of trains being stuck I really like to rename all my trains so they match the line they are on. However changing names on trains is currently quite cumbersome with having to use the "bring to view"-function->click on train->rename train.
Being able to directly rename trains in the line manager allows the user to quickly update all the names of trains on the same line to get a consistent experience

just click the train

Selecting the train is what this suggestion wants to avoid, it need to be found it first or retreive it in line manager, focus the view on it, click it, retry a few times because it moved and you missed it, then edit the name.
