The original code accumulates all the <td> texts between the description
link and the number of seeders into self.current_item["size"]:
<td>248.72</td><td> MB<td> => "248.72 MB".
ExtraTorrents changed the table design, added the Added column and joined
the number and its unit:
<td>8d</td><td>248.72 MB</td> => "8d 248.72 MB"
This commit stores only the last <td> text in self.current_item["size"].
