Shift-Rightclick on Train and Craft Stops to copy settings

[Rauschkind]

I can copy machine settings and stuff with shift rightclicks on other machines. Thats great!
Lets use this to copy settings of train and ship stops, too!

(i realize that its likely possible to have something like that with interrupts, that does not mean it would not be handy to have for normal stops too. rather, also add it to interrupts)
