Handles all the line breaks in calculation of line-character position

Handles:
        lineFeed = 0x0A,              // \n
        carriageReturn = 0x0D,        // \r
        lineSeparator = 0x2028,
        paragraphSeparator = 0x2029,
        nextLine = 0x0085,

Fixes #131
why is linePos assigned twice?
