Quotone can show a specific quote now

modified the Quotone plugin.

Now you can issue commands like
```
<alfateam123> !quotone 14
<Descartes> #14 - Megatokyo  1358 (Komugiko, Megatokyo, love)
<Descartes> All I’mma gonna do is let you get yer magical lil’ ass ta class right naow, so shut it! / An’ stop thinkin’ dat love fixes anythin’. It usually just screws things up.
```

If you're giving an invalid number (negative / higher than maximum quote at the time / not a number) to Descartes, it will show a random quote.
