- fixed small bug in menu button (preset dirs) in fileselect. When the menu

is empty (no $HOME/.Bfs and first time use of FileSelect) it was empty,
  causing a nasty drawing error.
  It now doesn't draw the menubutton when there are no preset dirs yet.

- removed 'unused variable' warnings from space.c
