More Fl_Tree doc improvements.
Only docs changed here, no code changed.. one method's definition moved to match similar method organization. Some redundant docs (for const vs. non-const) changed by referring the non-const method to the const one, to reduce size. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10081 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
