[BUG] Messages spammed by timeline updates (i.e. new/discontinued vehicles etc.)

[freddyhayward]

Currently, timeline updates spam the messages by appearing every time the game loads. On servers such as stephenson-siemens (see screenshot) and bridgewater-brunel before it became unplayable, this fills up the messages with the same repetitive notifications.

I made a pull request (https://github.com/jamespetts/simutrans-extended/pull/131) that stops the timeline from updating every load/save cycle - it still updates every month as it's supposed to. Can James or anyone else confirm that this will not affect actual gameplay - since I suspect that the results from the calculations done here are saved/loaded anyway? If it does, the notifications would need to be handled separately.

Thank you for your patch. I have made my own implementation of this, as your implementation had the potential to cause server/client desyncs, as actual calculations on initialisation/reload as well as messages were produced by the method the call to which you commented out. I also believe that it did not find all the references to it, so the version now implemented should work reliably in eliminating new game/load game message spam.

Thank you for your work on this, however.
