ssaparse enhancement to support completed Dialog lines
the ssaparse just parse the dialog lines with trimmed dialog lines. it requires the container parser to remove first 3 segment in dialog lines before sending to ssparse.
but some container parsers will just send the original dialog lines text which leading with "Dialog: , , , ...".
ssaparse should support this kind of buffer also.
besides if a buffer contains several lines of Dialog line, the ssaparse will only parse the first line.
