Make the destructor virtual.

(I thought I'd slip this in along with David's change to the default menu
configure option.  I believe that will cause a new config.h to be generated
which will cause a near complete rebuild of FG (as will this globals.hxx
change) so it shouldn't cause additional grief to have these happen at the
same time.)
