[Rseding91] [0.14.22] No mapgen options for scenarios in MP

[zx64]

Starting a script only scenario (i.e. control.lua but no blueprint.dat) in single player results in getting to specify the mapgen settings.
However, this option is not available when starting the game from the "Custom Scenario" option in the multiplayer menu, instead you go straight to the "Multiplayer lobby" dialog.

This is fixed in the next version of 0.15.
