Instead of a big std::string, buffer now store it's content in a list of lines. In order to achieve O(log(n)) random access, lines contains both their content and their offset since the start of the file, making binary search usable. BufferIterator now have a LineAndColumn coordinate into the buffer instead of an offset so that access is still O(1).
