Unable to set fs_userpath or fs_basepath

[DeathByDenim]

Commit 055d2a6 broke the parameters fs_userpath and fs_basepath. There used to be functions called fs_basepathChange and fs_userpathChange that would update BaseDirectory and UserDirectory, but they were replaced by CommandLineOnlyChange which doesn't update those variables.

This causes UserDirectory to be nil when running opensoldat like this:

./bin/opensoldat -fs_portable 0 -fs_userpath ~/temp/soldat/ -join 127.0.0.1 23073

Possible solution would be changing client/Client.pas:607--612 to this:

  begin
    if fs_userpath.Value = '' then
      UserDirectory := UserPathSDL
    else
      UserDirectory := IncludeTrailingPathDelimiter(fs_userpath.Value);
    if fs_basepath.Value = '' then
      BaseDirectory := BasePathSDL
    else
      BaseDirectory := IncludeTrailingPathDelimiter(fs_basepath.Value);
  end;

Though you may want to expand on that to create the directories if they don't exist.
