[Patch] FIX invert schedule function not working properly

[koroal]

Hello everyone!

I have discovered Simutrans a few days ago and I like it a lot!
That being said, if at all possible, I would like to contribute a few patches which rectify some problems that I have encountered. I will create a separate topic for every proposal.

This one fixes a problem with the button which is supposed, as I understand, to reverse the order of waypoints in a train's schedule. The current implementation stops one iteration earlier when the number of waypoints is even. As a result, the two waypoints in the middle of the schedule do not get swapped.

Out of curiosity, how did you come across Simutrans?.

I had heard about transportation and other economic simulations before, but had never actually look into them. Recently, I had been in a mood to try to play something like that. I had searched for the one transportation sim I had heard of at the time, and also for any alternatives that also would be playable on linux. Simutrans was another game that was often recommended in the search results and so I have tried it.
