[GunChleoc]

Execute map changes in Multiplayer UI after the player slots have been set. This fixes a bug with updating the client dropdowns.

Continuous integration builds have changed state:

Travis build 4045. State: passed. Details: https://travis-ci.org/widelands/widelands/builds/433322473.

[Klaus Halfmann (klaus-halfmann)]

Reproduced it on trunk, found it fixed here.

Looks like these monster switches in gameclient.cc deserve a refactoring :-)

One Comment inline.
