Is your feature request related to a problem? Please describe

The primary arrs (Prowlarr, sonarr, radarr) will build a permalink passed as <comments> element is RSS results in respective UI. This significantly enhances usability. Clicking on a result allows user to view all details that bitmagnet has on a torrent.

<div class="SearchIndexRow-sortTitle-sQqo7 SearchIndexRow-cell-PeDn7 VirtualTableRowCell-cell-_Qpcm TableRowCell-cell-giPrj" title="">

  <a href="**comments**" target="_blank" rel="noreferrer" class="Link-link-RInnp Link-to-kylTi" title="*redact*">
    <div>*redact*</div>
  </a>
</div>

Describe the solution you'd like

torznab spec and implementations done by arrs are not 100% inline. For completeness, populate:

• <comments> element
• <link> element
• coverurl attribute
  with same value "/webui/torrents/permalink/" + t.InfoHash.String()
