Fl_Table_Row: replace private class CharVector with std::vector

FL/Fl_Table_Row.H: use `std::vector<uint8_t> _rowselect;`,
  remove declaration of class `CharVector`

src/Fl_Table_Row.cxx: remove implementation of class `CharVector`,
  simplify loops (use range based for loops),
  use resize() to change vector size.

Unify copyright year of Fl_Table* headers and implementation.
