Merge lp:~hjd/widelands/scan-build-cmake into lp:widelands

[Hans Joachim Desserud]

Yesterday I learnt that it is sufficient to run `scan-build cmake` to have it replace the compiler in the necessary places. Thus there is no need to find and add the script manually. This should also expand cross-platform support quite a bit.

PS.
SirVer: I think this might work on OS X too now, if you want to test it. :)

Thanks! Merged.

I didn't try running scan-build. There are currently so much stuff going on with Widelands that I am not generating extra work for myself if I can avoid it :).
