[prototype]Mark where trains frequently get stuck at signals

[Michi_cc]

and I still put signals in front of my stations eventhough they have a build in signal since some time now (I just think it looks better).

They don't. What you see is simply the general don't-just-crash-my-trains protection. Just compare the position of the two waiting trains in http://www.tt-ms.de/forum/attachment.php?aid=1014.

Ah, OK. I assumed that they had like depots. Depots do have one built in them, don't they?
If not I have some more reading to do.

/me should stop assuming ...

Depots have signals built in. But as a train inside a depot has no real position anyway, it wouldn't make a difference where the train waits for a free path

I refreshed the patch:
- change: stuck counter now decreases to 0 so a highlight will disappear after certain period of time (previously once highlighted signal was staying highlighted for eternity)
- removed magic constants
- fixed coding style (whitespace)
- moved new functions in rail_map.h higher (to keep MakeXXX functions on the bottom as usually)
