Log class has the Stream class as a base class now

- implemented some missing operators<<(...)
- removed Manipulators: l1, l2, l3, l4, lend, lsave
- PascalCase to snake_case in Log

added to Stream:
  virtual bool is_char_stream() const = 0;
  virtual bool is_wchar_stream() const = 0;
  virtual char get_char(size_t index) const = 0;
  virtual wchar_t get_wchar(size_t index) const = 0;
  virtual Stream & operator<<(const Stream & stream) = 0;
