add minimap information layer for traffic jam

[bunnybot]

Add a minimap information layer for traffic jams (suggested by Tibor at [http://wl.widelands.org/forum/topic/42/]). This could be done by making the pixel red if the map node has a flag with at least 4 wares waiting. It is also worth considering to make the pixel redder the more wares are waiting at the flag. (To be implemented in calc_minimap_color, render.cc.)

work on this can start. It shouldn't be too hard to do.

I checked this, the implementation itself was not too hard. But the suggestion to make a red pixel where a flag has more than x wares is a bit unimpressive. First, it does not blend too well with a red player color. Second, on Winterland there are already orange pixels for normal flags in the flags layer (remember, on opening the window, all layers are active). Third, a single red pixel is not very visible on the terrain layer.

I guess we should find something else. Maybe a message from win conditions or exhausted mines?

Sometimes I wished the comments could be edited...

Last sentence should be:

"I guess we should find something else. Maybe a message like from win conditions or exhausted mines?"

Don't know what the proposed branch includes to fix this, but i think having the roads connected to a 'busy' flag colored red should be better visible.
