a new parameter: bool allow_skip_whitechars default true
added:   new methods: Toull_b(), Toll_b(), Toul_b(), Toui_b(), Tol_b(), Toi_b()
         automatically detects the base (radix):
           4323 - base 10
           0122 - base 8  (string starts with 0)
           #fff - base 16 (string starts with #)
           &101 - base 2  (string starts with &)
added:   CharType * SkipWhiteFromBack(CharType * str, bool check_additional_chars = true, bool treat_new_line_as_white = true)
         skipping white characters from the end of a string
changed: Toll_b(), Toull_b(), Tol_b() and Toul_b() are used in Space now
         for methods ToInt() etc so we are able to use a different base now
changed: some work in Space (const correctness)
