[gtkhtml] Skip \n and \r from whitespace recognition on HTML text paste

    Skip \n and \r from whitespace recognition on HTML text paste
    
    This fixes a bug in the previous commit. In case of a mutliline
    paste the new line markers are properly encoded within HTML tags,
    thus adding them as plain text resulted in doubled new lines.
