Subject: Fl_Tree API breaking changes (we haven't released 1.3.0 yet..):

    Fl_Tree::labelsize() -> item_labelsize()            -- TO AVOID COLLISION WITH Fl_Widget::labelsize()!
    Fl_Tree::labelfont() -> item_labelfont()            -- TO AVOID COLLISION WITH Fl_Widget::labelfont()!

Fl_Tree_Prefs (internal) changes:
    Fl_Tree_Prefs::fgcolor() -> labelfgcolor()          -- for consistency with above
    Fl_Tree_Prefs::bgcolor() -> labelbgcolor()          -- for consistency with above
    Fl_Tree_Prefs::selectcolor() removed                -- uses Fl_Widget::selection_color() instead
    Fl_Tree_Prefs::inactivecolor() removed              -- was unused; inactive color procedurally calculated

Other Fl_Tree mods:
    o Fixed bug with select_all(item) and deselect_all(item)
      (they were not limiting themselves to children of specified item)
    o Fixed bug with item not drawing in its /own/ bgcolor when item selected
    o Fl_Tree uses the Fl_Widget::selection_color()
    o All methods that deal with 'font types' changed int -> Fl_Font
    o All methods that deal with 'font sizes' changed int -> Fl_Fontsize
    o Added needed methods to Fl_Tree for accessing colors:

        item_labelfgcolor()     -- access default fg color used for new items
        item_labelbgcolor()     -- access default bg color used for new items
        tree_connectorcolor()   -- access the connector line color

    o Small doxygen comment adjustments and general clarifications
    o test/tree demo modified to include testing of new label color methods, cleanup
