Various small problems in timetable mode

[r.roeterdink]

Following problems occur :

- attach in #dispose at station : fails if train to which to attach exceeds platform length, and therefor attaching train cannot reach station.
Mod : if train to which to attach is stopped in station, set state for attaching train also to stopped at station

- callon sometimes fails
Mod : improve check on callon in relation to required station stop, check was sometimes too stringent

- activate sometimes fails
Mod : proper activation of other train was missing for some situations

- occupied track state sometimes is incorrect after attach
Mod : DistanceTravelled was not properly adjusted after attach and detach
Mod : Trigger distance for DistanceTravelledActions was not adjusted for changed train length

- endoftrack detection sometimes fails
Mod : Train can not be at end of route if it is not on its route

- wheels keep rotating when train terminates in pool
Mod : Add "Update(0)" when train is stored in pool

Refactoring :
- Use GetOtherTTTrainByNumber instead of GetOtherTrainByNumber
