Fl_Tree optimizations for selecting large trees (100k items).
Added _next_sibling and _prev_sibling to Fl_Tree_Item class to make
next_sibling() and prev_sibling() more efficient during item selection.
Used new FLTK_ABI_VERSION macro (as designed by Greg and Albrecht on fltk.dev) to protect the ABI breaking features.
