Merge lp:~widelands-dev/widelands/remove_signals into lp:widelands

[Tino]

I am proposing to merge this branch before b18, because:
- the CMake change regarding boost signals library is overdue. With the current state you are forced to compile the signals library to make the build work, even when it is not going to be linked.
- the activiation for the large address space on win32 should be safe. It was included in the windows test builds now for 5 weeks.

I agree on both issues. The windows thingy could even be seen as a bug fix and the other is definitively a build bug fix.
