The current more options window is too small. Also adding more options to it won't work. Thus we need to get more space for the options (f.e. with #4014). With this patch we remove the more option window and create a hide-able tabbed panel with all options (so the map options a re included there too). The hotkey and scroll features from rP20644 are used.
Also it is possible to have multiple columns of options, and that is automated, so if the options do not fit in one column, two columns will be created and filled with options.
When there are multiple columns in MP, the chat window can get so small it gets ugly, thus hiding the window when the space gets too small.
A problem still is that dropdowns very low in the screen are unusable, since the options are invisible.
Possibly the extended tag in the gamedescription need to be removed following this patch.
Also possibly the panel could be hidden on init in MP and showed in SP.
