Warning about files (pngs) not found when starting a new game

[Hans Joachim Desserud]

To reproduce:
1. Run widelands from the commandline.
2. Main menu -> Single player -> New game -> Checkmate -> Start game.
3. Watch the terminal output.

In addition to the usual messages, three errors about files not found are printed. Based on the double slash (//) there might be some minor error in a path somewhere (see the messages below).

I noticed these warnings recently so I think it is caused by a recent change (might have been after the roads changed?). I cannot remember seeing these errors earlier, and build16 does not print them when loading the same map.

Running Widelands bzr r5991 on Ubuntu 11.04.

First warnings:
Registering script: (aux,table)
Registering script: (aux,ui)

This is most likely based upon my patch that makes road texture world dependend. I will take a look into it.

Fixed in rev. 6013

later warning about sumpf_00.png is based upon the fact, that the new sumpf animations were not using indexed color palettes. I fixed this and run the png optimization script by that chance to get a bit smaller file sizes.
