Albrecht Schlosser ac76239db7 Remove scheme specific initialization from Fl_Tree_Prefs
This initialization would prevent changing the 'selectbox' type
automatically when changing the FLTK scheme.

It would also require to set the FLTK scheme *before* the constructor
of Fl_Tree_Prefs (i.e. Fl_Tree) is executed which is unexpected and
error prone for user code.

It is up to the user program to set another boxtype after the
constructor if needed.

Other platforms may use other symbols which can be reimplemented in the

pointing to the right, and an open branch with a triangle pointing down.
